Hi!
Im trying draw a quad with glDrawElements but I cant get this piece of code working:
setup:
// vertex array
float []vq={0, 0, 0, 5.0f, 0, 0, 5.0f, 4.0f, 0, 0,4.0f, 0};
// index array
int []iq={ 0, 1, 2, 3};
// make buffers
FloatBuffer verts=BufferUtils.createFloatBuffer(vq.length);
IntBuffer ind=BufferUtils.createIntBuffer(iq.length);
verts.put(vq);
ind.put(iq);
verts.flip();
ind.flip();
render:
GL11.glEnableClientState( GL11.GL_VERTEX_ARRAY );
GL11.glVertexPointer( 3,GL11.GL_FLOAT, verts);
GL11.glDrawElements(GL11.GL_QUADS, ind);
GL11.glDisableClientState( GL11.GL_VERTEX_ARRAY );
this renders nothing.. whats wrong?
-bez
Doh, wrong parameter..
GL11.glVertexPointer( 3,GL11.GL_FLOAT, verts);
must be
GL11.glVertexPointer( 3, 0, verts);
