  • Constructor Details

    • VertexProgramState

      public VertexProgramState()
      Creates a new VertexProgramState. load(URL) must be called before the state can be used.

  • Method Details

    • setEnvParameter

      public static void setEnvParameter(float[] param, int paramID)
      setEnvParameter sets an environmental vertex program parameter that is accessible by all vertex programs in memory.
      Parameters:
      param - four-element array of floating point numbers
      paramID - identity number of the parameter, ranging from 0 to 95

    • setParameter

      public void setParameter(float[] param, int paramID)
      setParameter sets a parameter for this vertex program.
      Parameters:
      param - four-element array of floating point numbers
      paramID - identity number of the parameter, ranging from 0 to 95

    • getType

      public RenderState.StateType getType()
      Specified by:
      getType in class RenderState
      Returns:
      An statetype enum value for the subclass.
