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];
