Class GLStateComponentIF

java.lang.Object
  hmi.graphics.opengl.state.GLStateComponentIF

All Implemented Interfaces:

GLRenderObject, GLStateComponent

public class GLStateComponentIF
extends Object
implements GLStateComponent

A GLStateComponentIF is a wrapper for GL attributes that are set by means of a call like glXYZ(glEnum, glId, glValf), where glEnum and glId are ints, glValf is a float value. Examples: glLightf with glEnum == light, glId == GL_SPOT_EXPONENT, GL_SPOT_CUTOFF, GL_CONSTANT_ATTENUATION, GL_LINEAR_ATTENUATION, GL_QUADRATIC_ATTENUATION. glMaterialfv with glEnumi == face, glId == GL_SHININESS glTexParameterfv with glEnumi == target, glId == GL_TEXTURE_MIN_LOD, GL_TEXTURE_MAX_LOD
