Title: LWJGL Exception thrown having processed a VBO...
Post by: plummew on June 19, 2007, 23:43:12

Hi,

Can anyone shed light on the following exception:

Exception in thread "main" org.lwjgl.opengl.OpenGLException: Cannot use Buffers when Array Buffer Object is enabled
at org.lwjgl.opengl.GLChecks.ensureArrayVBOdisabled(GLChecks.java:84)
at org.lwjgl.opengl.GL11.glVertexPointer(GL11.java:2528)

I've previously rendered a VBO using glDrawRangeElements and the exception above is thrown when I attempt to set the vertex pointer for a vertex array (not a VBO)

Any ideas? (I assumed I could mix and match vert arrays and VBOs...)

You need to call

Code Select

ARBVertexBufferObject.glBindBufferARB(ARBVertexBufferObject.GL_ARRAY_BUFFER, 0); before you can use vertex arrays again.

Ciao Matthias

Cheers,

That did the trick.

As I was buffering indices, I needed to unbind GL_ELEMENT_ARRAY_BUFFER_ARB too.
