Method Detail

textureGetMaximumSize

int textureGetMaximumSize()
                   throws JCGLException

Returns:

The maximum texture size supported by the current implementation. 'Size' refers to the length of a side, so if the implementation returns 8192, the largest texture that can be created is 8192 * 8192.

Throws:

JCGLException - Iff an OpenGL error occurs.

textureGetUnits

List<JCGLTextureUnitType> textureGetUnits()
                                   throws JCGLException

Returns:

All available texture units for the current implementation.

Throws:

JCGLException - Iff an OpenGL error occurs.

textureUnitIsBound

boolean textureUnitIsBound(JCGLTextureUnitType unit)
                    throws JCGLException

Parameters:

unit - The texture unit.

Returns:

true iff the the texture unit unit has any texture bound to it.

Throws:

JCGLException - Iff an OpenGL error occurs.

textureUnitUnbind

void textureUnitUnbind(JCGLTextureUnitType unit)
                throws JCGLException

Unbind whatever texture is bound to the texture unit unit (if any).

Parameters:

unit - The texture unit

Throws:

JCGLException - Iff an OpenGL error occurs.
