Protected Member Functions | |

| Int32 version |
[READ ONLY] The version number of the structure.
| Int32 fps |
[READ ONLY] The frames per second.
| Vector ambient |
[READ ONLY] The global ambient component.
| Float time |
[READ ONLY] The current time in seconds.
| Vector col |
[READ WRITE] Set the calculated color within MaterialData::CalcSurface() and MaterialData::CalcVolumetric().
| Vector trans |
[READ WRITE] Set the calculated transparency within MaterialData::CalcSurface(), MaterialData::CalcTransparency() and MaterialData::CalcVolumetric().
| Vector refl |
[READ WRITE] Set the calculated reflection within MaterialData::CalcSurface().
| Float alpha |
[READ WRITE] Set the calculated alpha within MaterialData::CalcAlpha().
| Ray* tray |
[READ WRITE] The transmitted vector (can be modified in MaterialData::ChangeNormal()), only valid if shader sets VOLUMEINFO::TRANSPARENCY and only during MaterialData::CalcSurface().
| Ray* rray |
[READ WRITE] The reflected vector (can be modified in MaterialData::ChangeNormal()), only valid if shader sets VOLUMEINFO::REFLECTION and only during MaterialData::CalcSurface().
| Vector64 p |
[READ WRITE] The surface point, this can only be modified by MaterialData::Displace().
| Vector64 bumpn |
[READ WRITE] The surface phong and bump normal.
| Ray* ray |
[READ ONLY] The current eye ray. Always valid, not nullptr.
| Vector64 orign |
[READ ONLY] The original surface normal.
| Vector64 n |
[READ ONLY] The surface phong normal.
| Vector64 dispn |
[READ ONLY] The suggested displacement direction.
| Float64 cosc |
[READ ONLY] The angle between ray vector and unbumped normal.
| Vector uvw |
[READ ONLY] The surface UVW coordinates, this is invalid for volumetric shaders.
| Vector delta |
[READ ONLY] The MIP sample radius. Defines the radius for the area around UVW that needs to be sampled.
If this value is ignored by a shader, it will work, but produce aliasing artefacts.
| RayHitID lhit |
[READ ONLY] The surface identity.
| const TexData* tex |
[READ ONLY] The surface texture, never change this pointer.
| Vector ddu |
[READ ONLY] U direction vector perpendicular to n; can be used for bump mapping if VOLUMEINFO::DUDVREQUIRED is set.
| Vector ddv |
[READ ONLY] V direction vector perpendicular to n; can be used for bump mapping if VOLUMEINFO::DUDVREQUIRED is set.
| Int32 raydepth |
[READ ONLY] The depth of the actual ray.
| Int32 calc_trans |
[READ ONLY] Specifies if transparency will be rendered:
| Int32 calc_refl |
[READ ONLY] Specifies if reflections will be rendered:
| Bool calc_shadow |
[READ ONLY] Specifies, if shadows will be rendered.
| Int32 calc_illum |
[READ ONLY] Specifies, if illumination will be rendered.
If this value is 0 then VolumeData::CalcSurface() should directly return the surface color without illumination (also, no bump mapping is needed in VolumeData::ChangeNormal() etc.). This technique is used for some types of objects like the sky. Illuminance1 automatically takes care of calc_illum.
| Int32 calc_mip |
[READ ONLY] Specifies if MIP calculations will be done.
If this value is 0 then no MIP mapping needs to be calculated. calc_mip can in some cases be false, even if the shader sets VOLUMEINFO::MIPSAT::
If calc_mip is false you should not access MIP/SAT variables such as delta etc.
| Vector pp[3] |
[READ ONLY] MIP corner points in global space.
| Vector nn[3] |
[READ ONLY] MIP normals of the three other corner points.
| const RayLight* xlight |
The light source during shadow evaluation. Can be nullptr, always check.
| const RayObject* op |
The object. Can be nullptr, always check.
| Int32 recursion_id |
[READ WRITE] The plugin ID of data passed through recursion.
| void* recursion_data |
[READ WRITE] The address of data passed through recursion.
| Multipass* multipass |
[READ WRITE] To be filled for multipasses.
| Vector back_p |
[READ ONLY] The back-projected point (StickTextureTag) will be generated if the shader sets the flag VOLUMEINFO::TRANSFORM or SHADERINFO::TRANSFORM for a channel shader.
| Vector back_delta |
[READ ONLY] This the 'spot size' (MIP mapping value) for the back-projected point.
The back-projected point (StickTextureTag) will be generated if the shader sets the flag VOLUMEINFO::TRANSFORM (or SHADERINFO::TRANSFORM if it is a channel shader).
| Float global_mip |
[READ ONLY] The global MIP scale.
| Int32 sid |
[READ ONLY] Sub-polygon ID (only used for SPD).
| Float par_u |
[READ ONLY] Barycentric U coordinate (only used for SPD).
| Float par_v |
[READ ONLY] Barycentric U coordinate (only used for SPD).
| SurfaceIntersection* intersection |
[READ ONLY] The intersection data. Can be nullptr, always check.
| Float mb_offset |
[READ ONLY] The motion blur time offset. (Between 0.0 and 1.0, only valid in Physical Render.)
| Vector comp_color |
[READ WRITE] The diffuse component of the calculated color.
| Vector comp_specular |
[READ WRITE] The specular component of the calculated color.
| Vector comp_luminance |
[READ WRITE] The luminance component of the calculated color.
| TexEntry* rtex[4] |
[READ ONLY] Internal. The reflection textures.
| Int32 elementIndex |
[READ ONLY] Internal. Stores the index of the currently rendering hair. May be extended to other object types eventually.
| const RayPolyWeight* displacementWeight |
[READ ONLY] Private.
