Constructor for the GLSL program sent to vertex and fragment shaders, including default uniforms and attributes.
// = object.matrixWorld
uniform mat4 modelMatrix;
// = camera.matrixWorldInverse * object.matrixWorld
uniform mat4 modelViewMatrix;
// = camera.projectionMatrix
uniform mat4 projectionMatrix;
// = camera.matrixWorldInverse
uniform mat4 viewMatrix;
// = inverse transpose of modelViewMatrix
uniform mat3 normalMatrix;
// = camera position in world space
uniform vec3 cameraPosition;
// default vertex attributes provided by Geometry and BufferGeometry
attribute vec3 position;
attribute vec3 normal;
attribute vec2 uv;
Note that you can therefore calculate the position of a vertex in the vertex shader by:
gl_Position = projectionMatrix * modelViewMatrix * vec4(position, 1.0);
or alternatively
gl_Position = projectionMatrix * viewMatrix * modelMatrix * vec4(position, 1.0);

#elif defined(USE_COLOR)
// vertex color attribute

// Note that modelViewMatrix is not set when rendering an instanced model,

//
// Basic Usage:
// gl_Position = projectionMatrix * viewMatrix * modelMatrix * instanceMatrix * vec4(position, 1.0);
