Implement BTDF parsing and its public API

2026-02-25T17:39:20Z

commit ceda1f093bce8ca07861f661c86067b40febb55b parent db820201ae9a8f31d402e242938b4fa4aeccd353 Author: Eduardo Fontana Lazzari Date: Wed, 25 Feb 2026 18:39:20 +0100 Implement BTDF parsing and its public API This commit adds support for parsing the new Bidirectional Transmissivity Distribution Function (BTDF), recently introduced in the configuration file specification. It also extends the public Sphin API with new elements that allow clients to retrieve BTDF properties. Since BTDF and BRDF are closely related concepts, the BTDF API (both public and internal) was designed based on its reflectivity counterpart. BRDF and BTDF tests were refactored and moved to a dedicated test file as test_sphin_load_surface was becoming overly large.

Update BRDF parsing accordingly to the new config file specification

2026-02-24T17:17:08Z

commit db820201ae9a8f31d402e242938b4fa4aeccd353 parent 3ae3162665bbe7bcec40722f7e5490386a44d6cb Author: Eduardo Fontana Lazzari Date: Tue, 24 Feb 2026 18:17:08 +0100 Update BRDF parsing accordingly to the new config file specification Take the new BRDF reflectivity options into account when parsing a configuration file. This commit also simplifies the sphin API for BRDFs by decoupling the energetic component (i.e., the directional–hemispherical reflectivity) from the reflection direction distribution PDF, following a similar approach to that used for surface sources. The public sphin API introduces a new enum, sphin_brdf_reflectivity_type, to represent the different reflectivity options now supported in the configuration file. Additionally, sphin_brdf_type has been renamed to the more appropriate sphin_brdf_direction_distribution. Reflectivity, previously represented as a real value, is now treated as a spectral property (although it may be spectral-directional). Tests have been updated accordingly.

Add BTDF concept and new BRDF types to the format file specification

2026-02-10T18:05:54Z

commit 3ae3162665bbe7bcec40722f7e5490386a44d6cb parent 0abe6e70f3587d465311907306cfc409441a31c4 Author: Eduardo Fontana Lazzari Date: Tue, 10 Feb 2026 19:05:54 +0100 Add BTDF concept and new BRDF types to the format file specification Current possibilities for interface scattering may be considered limiting, as only a small set of phenomena in interfaces can be represented by currently existing BRDFs. Furthermore, the format file specification is not explicit about the geometrical optics models, although media can have refraction indices. This commit introduces a new type of BRDF to the format file specification which explicitly states to use the refractive indices of each side of an interface to describe light scattering in a given surface, but also introduces a new concept to the format file specification, the BTDF (bidirectional transmittance distribution function) which allows one to prescribe the intensity of the incoming light that crosses a given surface and how it should behave once it crosses it.

Correction to the star-phor-input manual page.

2026-02-24T10:35:37Z

commit 0abe6e70f3587d465311907306cfc409441a31c4 parent c5b9f4841f6ba57d3a2b530570855246debe7087 Author: Vincent Forest Date: Tue, 24 Feb 2026 11:35:37 +0100 Correction to the star-phor-input manual page. Transform the system's ASCII art into comments in the example files. This way, the ASCII art is formatted as literal text, as expected, since ASCII art must be verbatim. Adding these drawings as comments in the example files also illustrates how comments can be used to help describe the system, directly in the file sources. Beyond formatting alone, this change corrects the generation of the manual page: the scdoc format uses spaces and tabs at the beginning of lines as part of its language. As a result, ASCII art caused errors due to non-compliance with this grammar. Finally, note the modification of ASCII arts to display backslash characters. These are used by scdoc to escape another character. They must therefore be escaped themselves in order to be displayed.

Change format specification for prop_rad type in star-phor-input

This commit introduces a new format for the prop_rad type (currently only applied to scatterers) to standardize element declarations and improve overall coherence of the configuration file. As a compromise, an additional indentation level is added (although the underlying abstraction layer was already present). Docs, parsing, and tests have been updated accordingly.

The new structure `sphin_refractive_index` is composed of two spectral properties as member variables: one for the real part and one for the imaginary part of the refractive index. Thus, each one of these two variables benefit from the full `sphin_spectral_property` API (descriptor, interpolation, etc.). Each part of the refractive index (real and imaginary) is also independent in the input file. This approach was chosen as it simplifies parsing, ensures decoupling between the two parts of the refractive index, and minimizes the amount of new code.

Change parsing logic for sphin_prop_rad name and type

commit ec938886fb5456883cdbc0ed91b12c5eb4acb8f4 parent a11874485c0f409fa00b1db4d361729e675e852c Author: Eduardo Fontana Lazzari Date: Sat, 4 Oct 2025 17:52:52 +0200 Change parsing logic for sphin_prop_rad name and type prop_rads are declared in the input file as prop_rad: "name" TYPE. Until now, a simple parsing strategy was used: the "name" TYPE part was tokenized using spaces and tabs as separators. The first token was treated as the name, and the last token as the type or radiative property. This approach caused bugs when spaces were included in "name" (which is allowed in the input file). To address this issue, the parsing logic was replaced. Now, it first uses the quotation marks (") as delimiters to extract the name, then interprets the remaining part of the string as the prop_rad type. As before, no characters other than spaces and tabs are allowed outside the name and type.

Expose getter functions for volume, surface, and prop_rad names

2025-10-04T15:17:58Z

commit 32fab332c807c21a470b8b8fd7d980ad553662d0 parent 47828fa38176281f606a1419e457b8cfc306350b Author: Eduardo Fontana Lazzari Date: Sat, 4 Oct 2025 17:17:58 +0200 Expose getter functions for volume, surface, and prop_rad names The name of each of these structures is defined in the input file and therefore forms part of the photoreactor system description. To make this information accessible to client applications, the star-phor-input API now provides getter functions to retrieve these names. This commit additionally adds corresponding unit tests for volume, surface, and prop_rad name getters and does minor formatting and comment improvements in sphin.h.

Add interp method to interpolation function

commit 283f82b38a7b3c867accf2f0a3a1b2e2132ebd11 parent ed1549d80066aabc1b21e3dc5818e66331019651 Author: Eduardo Fontana Lazzari Date: Mon, 8 Sep 2025 14:08:57 +0200 Add interp method to interpolation function Although only linear interpolation is currently supported, it is very likely that in the future developers may want to test different interpolation methods. Adding the interpolation method as a function argument anticipates the use of other methods and prevents future API breaks due to changes in the function prototype when a new method is added.

Introduces spectral properties framework

2025-08-25T15:07:29Z

commit ed1549d80066aabc1b21e3dc5818e66331019651 parent 70bb72288ba6d6d31e8229807c09e6c3592b1b27 Author: Eduardo Fontana Lazzari Date: Mon, 25 Aug 2025 17:07:29 +0200 Introduces spectral properties framework Up to this point, all physical properties in sphin have been supported as 'doubles'. However, in photoreactive systems, spectral (i.e., per-wavelength) properties are often necessary to fully describe the system and the underlying physics. This is the case for the radiative properties of particles and the emission properties of sources, which may vary significantly across the electromagnetic spectrum. These properties can also be expressed in different ways depending on the situation. The absorption properties of a particle, for instance, may be represented as an absorption coefficient or as absorption cross sections. They may also be computed using Mie theory. From an implementation perspective, this translates into a structure that can easily become complex. This commit introduces the numerical structure that allows applications using sphin to handle spectral properties, covering a broad range of the possibilities currently used in photoreactive systems engineering. A generic structure, sphin_spectral_property, is added. It contains two lists of equal length: one with the wavelengths and the other with the corresponding property values. Physical properties can be constructed upon this structure. Similar to the representation of geometries, it uses rsys internally to simplify operations and is exposed with a descriptor containing simpler types to streamline interactions through the sphin API. This commit also begins implementing some of the derived structures that use sphin_spectral_property, such as absorption cross sections and emission spectra. For now, backward compatibility with scalar properties (such as ka) is preserved.

Additionally, examples illustrating the chosen conventions are added to make the documentation more clear and illustrative.

Extend BRDF API to allow retrieval of type

This commit also updates the test to use a more appropriate value for verification.

Fix: return NULL when volume is not a sensor

2025-07-09T16:36:45Z

commit d45ffad5d51039b641be20cb7a15bdfd105a783d parent 55db9d064e592ed010d5e2420f0bb2be2fecfa8f Author: Eduardo Fontana Lazzari Date: Wed, 9 Jul 2025 18:36:45 +0200 Fix: return NULL when volume is not a sensor The function sphin_volume_get_sensor should accept volumes that are not sensors. In such cases, the correct behavior is to return NULL as the sensor and the response status RES_OK — both for consistency with how surface_sources are handled, and to allow library users to easily check whether a volume is a sensor via the API. This was not the case previously, and this commit fixes that behavior.

Refactor: Add suffixes to sensor and source structs/functions

2025-05-21T15:56:09Z

commit 55db9d064e592ed010d5e2420f0bb2be2fecfa8f parent d455bd9660c60a24525c3d4450841465be11a4f3 Author: Eduardo Fontana Lazzari Date: Wed, 21 May 2025 17:56:09 +0200 Refactor: Add suffixes to sensor and source structs/functions Although the concepts of sources and sensors are common to both surfaces and volumes, their definitions (both in a physical problem, and in the numerical representation, as consequence) differ significantly between the two cases. Up to this point, there was only one definition for the source struct, which corresponded to surface sources, and a single sensor struct that included only one member variable, response_function, which happens to be shared by both volume and surface sensors. Because only a small subset of member variables is common to both volume and surface implementations, it makes sense to define separate structs for each physical entity. In this commit, the original sensor struct has been split into sphin_sensor_surface and sphin_sensor_volume, reflecting their specific contexts. Where functionality is shared —such as in parse_response_function — it has been preserved across both implementations. Additionally, all existing source references have been renamed with the _surface suffix, as the current implementation supports only surface sources. Volume sources will be introduced in a new source_volume struct in subsequent work.

Add Surface API function to get total emitted power

2025-05-21T13:03:17Z

commit d455bd9660c60a24525c3d4450841465be11a4f3 parent 86bd7c698a0127dfc4b851c0ff4ba4a6d1080844 Author: Eduardo Fontana Lazzari Date: Wed, 21 May 2025 15:03:17 +0200 Add Surface API function to get total emitted power In the star-phor-input file, the user specifies the flux of a surface source as a power density (i.e., power per unit area). However, during a computation, it may be useful to obtain the total power emitted by the surface, not just the specific power density. This commit introduces a function in the surface API to compute and retrieve the total emitted power from a surface, provided it is a source. Note that this function is added to the Surface API rather than the Source API. This design decision is due to the fact that computing total power requires knowledge of the surface's geometry, which resides within the surface struct. In the current architecture, sources are agnostic of the surfaces they are associated with. Hence, the function logically belongs to the surface API.

This makes formatting easier, but removes any possibility of stylization: only plain ASCII text is allowed. As a result, verbatim grammar entries are placed in single quotation marks where they were formatted in bold. The grammar has been simplified by removing the optional comment at the end of each line. Although this is not strictly accurate, given that a comment can indeed be added at the end of a line, the change nevertheless makes the grammar much lighter to read, and the example shows that a comment can indeed be added at the end of a line. If that's not enough, someone could explain it in the introductory text to the grammar. The grammar text is formatted so as not to exceed 80 columns. This ensures that its formatting is compatible with a legacy terminal or, more generally, with line-width constraints, for example when HTML formatting is intended. Some grammar rules have therefore been renamed to make them more compact, trying to ensure that they remain sufficiently explicit with regard to what they represent. Add the StL reference to the “See also” section. Finally, automate the generation of the man page when the install target is invoked.

Additionally, further ASSERTs have been added to parsing functions, abstracting those previously performed by callers.

Line numbering was incremented after each read operation, both at the root level (config) and in its sublevels (volume, surface, source). With the evolution of the input file format, multiple levels of branching are now possible (e.g., config -> surface -> sensor), forming a tree structure. This led to an issue where, after parsing the last line of the deepest structure, the line number was incremented twice, causing one line to be skipped. To fix this, line number incrementation is now handled by each parsed line at the deepest level of the tree structure (its leaves), independent of depth.

Refactor code for geometry

2025-02-28T11:39:41Z

commit 6c0027c4484695de150618eabd70c2005032240e parent 929065804bbd102cc7fed988630c2925eb9d59e0 Author: Eduardo Fontana Lazzari Date: Fri, 28 Feb 2025 12:39:41 +0100 Refactor code for geometry The new sphin_geometry struct replaces the old geometry struct, now storing geometry data as two arrays: one for vertices coordinates and one for its indices. This change is essential for upcoming features in the sphin library, including the computation of quantities dependent on geometry, such as the total flux emitted by a source (which depends on its area for surface sources or volume for volume sources). Additionally, this refactor abstracts the storage format, making the library caller agnostic of how geometry is stored on disk. Instead of handling a simple file path, the library now provides all necessary data directly in array form.
