Class GLKEffectPropertyLight

  • All Implemented Interfaces:
    NSObject
    public class GLKEffectPropertyLight
extends GLKEffectProperty
    GLKEffectPropertyLight GLKEffectPropertyLight provides a single directional or spot light for an GLKEffect in accordance with the OpenGL ES 1.1 specification. Per the OpenGL ES 1.1 specification, light position and directions are transformed by the modelview matrix. Accordingly, GLKEffectPropertyLight has a transform property. If light transformation is required the transform property must be explicitly set for light properties. In order for lighting calculations to function properly, clients of GLKEffectPropertyLight must enable the vertex attribute array GLKVertexAttribNormal to provide normals for lighting calculations. The normals are always normalized. The default values for GLKEffectPropertyLight properties are as follows: { 0, 0, 1, 0}, // position { 0, 0, 0, 1}, // ambient color { 1, 1, 1, 1}, // diffuse color { 1, 1, 1, 1}, // specular color { 0, 0, -1}, // spot direction 0, // spot exponent 180, // spot cutoff 1, // constant attenuation 0, // linear attenuation 0, // quadratic attenuation Note that, as with OpenGL ES 1.1 differentiation between a directional and spot light pivots on the value specified for _spotCutoff. A _spotCutoff of 180.0, the default value, indicates a directional light while values less than 180.0 indicates a spot light.
