Detailed Description

Header file describing the RED::RenderShader class, that is the shader class leveraging programmable graphics hardware.

Macro Definition

RED_LIGHT_DIRECTIONAL: Type of a light source identifying a directional light. A directional light is defined by the light source axis system. It emits its light in the sight axis direction. A directional light has no attenuation equation, and emits lights in the whole scene space.

RED_LIGHT_BEAM: Type of a light source identifying a light beam. A light beam is a directional light whose effect area is reduced to a cylindrical region of space. The light source axis system defines the cylinder referential. The beam light may have an attenuation.

RED_LIGHT_SUN_LIGHT: Type of a light source identifying a physical sun light.

RED_LIGHT_MOON_LIGHT: Type of a light source identifying a physical moon light.

RED_LIGHT_POINT: Type of a light source identifying an omnidirectional light.

RED_LIGHT_AREA: Type of a light source identifying an area area light source. An area light source is made of lighting and shadowing samples. These lights produce smooth shadowing effects.

RED_LIGHT_POINT_SPOT: Type of a light source identifying a point light spot. The spot uses the light source axis system . Spot direction is along the sight axis of the light’s system. The maximal angle of a spot falloff is RED_PI/2 (the sum of the spot angle and falloff).

RED_LIGHT_AREA_SPOT: Type of a light source identifying an area light spot. Is similar to the RED_LIGHT_POINT_SPOT. The apex of the spot cone is located at the center of the area light sphere, and therefore cuts its effect in its containment sphere.

RED_LIGHT_NO_LIGHT: Flag used by the RenderShader to indicate that a parameter is not to be used with any kind of light.

RED_LIGHT_AMBIENT_LIGHT: Type of a light indicating an ambient light.

RED_LIGHT_SKY_LIGHT: Type of a light indicating a sky light.

RED_LIGHT_PHYSICAL_LIGHT: Type of a light indicating a physical light.

RED_SHAD_TARGET_LIGHT_DIRECTIONAL: Shader target flag indicating that we only target directional lights parameters.

RED_SHAD_TARGET_LIGHT_BEAM: Shader target flag indicating that we only target beam lights parameters.

RED_SHAD_TARGET_LIGHT_POINT: Shader target flag indicating that we only target point lights parameters.

RED_SHAD_TARGET_LIGHT_AREA: Shader target flag indicating that we only target area lights parameters.

RED_SHAD_TARGET_LIGHT_NO_LIGHT: Shader target flag indicating that we only target parameters that are not related to lighting.

RED_SHAD_TARGET_LIGHT_SKY_LIGHT

RED_SHAD_TARGET_REFLECTION_VECTOR: Shader target flag indicating that we only focus on direct reflection vector calculation parameters.

RED_SHAD_TARGET_INDIRECT_REFLECTION_VECTOR: Shader target flag indicating that we only focus on indirect reflection vector calculation parameters.

RED_SHAD_TARGET_INDIRECT_REFRACTION_CUTOFF: Shader target flag indicating that we only focus on indirect refraction cutoff calculation parameters.

RED_SHAD_TARGET_GI_DIFFUSE_COLOR: Shader target used to identify the diffusion color used for GI computations.

RED_SHAD_TARGET_GI_REFLECTION_COLOR: Shader target used to identify the reflection color used for GI computations.

RED_SHAD_TARGET_GI_TRANSMISSION_COLOR: Shader target used to identify the transmission color used for GI computations.

RED_SHAD_TARGET_GI_NORMAL: Shader target used to identify the normal direction used for GI computations.

RED_SHAD_TARGET_GI_NORMAL_INDIRECT: Shader target used to identify the normal direction used for GI computations.

RED_SHAD_TARGET_SOFT_KILL: Shader target used to identify software ray-tracer pixel kill shaders that mimic the behavior of the shader ‘KIL’ statement. This target goes to a regular rendering pass and not to the RED::MTL_RAYTRACE pass. Note that this target can’t be associated to any state shader data. It only describes the parameters that are needed to decide on killing a fragment or not.

RED_SHAD_TARGET_BSDF: Shader target used by BSDF shaders. Those shaders are needed to support path tracing rendering in RED. Currently, this target is reserved for internal use.

RED_SHAD_TARGET_ANY_LIGHT: Material target flat indicating that we focus on accessing parameters from any kind of light.
