Class GLStateComponentIF4

java.lang.Object
  hmi.graphics.opengl.state.GLStateComponentIF4

All Implemented Interfaces:

GLRenderObject, GLStateComponent

public final class GLStateComponentIF4
extends Object
implements GLStateComponent

A GLStateComponentIF4 is a wrapper for GL attributes that are set by means of a call like glXYZ(glEnum, glId, glValfv), where glEnum and glId are ints, glValfv is a float[4] value. Examples: glLightfv with glEnum == light, glId == GL_AMBIENT, GL_DIFFUSE, GL_SPECULAR, GL_POSITION, GL_SPOT_DIRECTION (last one is float[3]) glMaterialfv with glEnumi == face, glId == GL_AMBIENT, GL_DIFFUSE, GL_SPECULAR, GL_EMISSION glTexParameterfv with glEnumi == target, glId == GL_TEXTURE_BORDER_COLOR
