Detailed Description
ShaderProgram class encapsulates a shader program. A shader program consists of several different shaders, such as vertex and fragment shaders.
Qt3D will automatically populate a set of default uniforms if they are encountered during the shader instrospection phase.
| Default Uniform | Associated Qt3D Parameter name | GLSL declaration | |||
|---|---|---|---|---|---|
| ModelMatrix | modelMatrix | uniform mat4 modelMatrix; | |||
| ViewMatrix | viewMatrix | uniform mat4 viewMatrix; | |||
| ProjectionMatrix | projectionMatrix | uniform mat4 projectionMatrix; | |||
| ModelViewMatrix | modelView | uniform mat4 modelView; | |||
| ViewProjectionMatrix | viewProjectionMatrix | uniform mat4 viewProjectionMatrix; | |||
| ModelViewProjectionMatrix | modelViewProjection mvp | uniform mat4 modelViewProjection; uniform mat4 mvp; | |||
| InverseModelMatrix | inverseModelMatrix | uniform mat4 inverseModelMatrix; | |||
| InverseViewMatrix | inverseViewMatrix | uniform mat4 inverseViewMatrix; | |||
| InverseProjectionMatrix | inverseProjectionMatrix | uniform mat4 inverseProjectionMatrix; | |||
| InverseModelViewMatrix | inverseModelView | uniform mat4 inverseModelView; | |||
| InverseViewProjectionMatrix | inverseViewProjectionMatrix | uniform mat4 inverseViewProjectionMatrix; | |||
| InverseModelViewProjectionMatrix | inverseModelViewProjection | uniform mat4 inverseModelViewProjection; | |||
| ModelNormalMatrix | modelNormalMatrix | uniform mat3 modelNormalMatrix; | |||
| ModelViewNormalMatrix | modelViewNormal | uniform mat3 modelViewNormal; | |||
| ViewportMatrix | viewportMatrix | uniform mat4 viewportMatrix; | |||
| InverseViewportMatrix | inverseViewportMatrix | uniform mat4 inverseViewportMatrix; | |||
| AspectRatio (surface width / surface height) | aspectRatio | uniform float aspectRatio; | |||
| Exposure | exposure | uniform float exposure; | |||
| Gamma | gamma | uniform float gamma; | |||
| Time (in nano seconds) | time | uniform float time; | |||
| EyePosition | eyePosition | uniform vec3 eyePosition; | |||
| SkinningPalette | skinningPalette[0] | const int maxJoints = 100; uniform mat4 skinningPalette[maxJoints]; | |||
