Member Function Documentation

virtual unsigned long GLFX::IIndexBuffer::GetSize

(

)

[pure virtual]

Returns number of elements.

Returns:

number of element

virtual GLenum GLFX::IIndexBuffer::GetType

(

)

[pure virtual]

Returns element type.

Returns:

element type: GL_UNSIGNED_BYTE, GL_UNSIGNED_SHORT, or GL_UNSIGNED_INT.

virtual void* GLFX::IIndexBuffer::Lock

(

GLenum

access

)

[pure virtual]

Locks vertex buffer and returns pointer to memory.

Parameters:

access

access mode (GL_READ_ONLY, GL_WRITE_ONLY, or GL_READ_WRITE); 0 -- default access mode (write only)

virtual void GLFX::IIndexBuffer::Unlock

(

)

[pure virtual]

Unlocks vertex buffer. Memory pointer returned by Lock() is no longer valid.

virtual void GLFX::IIndexBuffer::Bind

(

)

[pure virtual]

Binds buffer and enables drawing.

virtual void GLFX::IIndexBuffer::Unbind

(

)

[pure virtual]

Disables rendering from this vertex buffer.

virtual void GLFX::IIndexBuffer::DrawElements	(	GLenum	mode,
		GLsizei	first,
		GLsizei	count
	)			[pure virtual]

Draws elements from this buffer.

Parameters:

	mode	the kind of primitve to render: GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_QUAD_STRIP, GL_QUADS, and GL_POLYGON.
	first	first element to begin with
	count	number of elements to draw
