Title: Problem migrating to direct buffers
Post by: Eistoeter on February 23, 2010, 16:05:48

Hello,

I've updated to LWJGL 2.3 and can't get my buffers working correctly. I got exceptions that LWJGL does no longer support indirect buffers so I updated my buffers.

The problem is, that I don't get anything displayed on the screen the way it should be. Now I only get bizzare graphic errors. Here is my code as it was before:

Code Select


FloatBuffer buf = FloatBuffer.allocate(16);
		getLocalRotationMatrix().store(buf);
		buf.flip();
		GL11.glMultMatrix(buf);

and here the new code:

Code Select


ByteBuffer byteBuffer = ByteBuffer
				.allocateDirect((Float.SIZE / 8) * 16);
		FloatBuffer floatBuffer = byteBuffer.asFloatBuffer();
		getLocalRotationMatrix().store(floatBuffer);
		floatBuffer.flip();
		GL11.glMultMatrix(floatBuffer);

Can you tell me what I do wrong?

Solved using BufferUtils
