Hi,
I have written a small library using cl-opengl to do skeletal animation
which works great.
I use vertex arrays in the process. As outlined in opengl-array.lisp under
examples, I have
a gl array of vertices.
To the vertex object in the gl array I added texture coordinates:
(gl:tex-coord :type float :components (u v))
In my code, (just like enable vertex and color array); I enable tex coord
array
; all texture loading code and creating gl vertices/indices code
(gl:enable-client-state :texture-coord-array)
.......
(gl:bind-gl-vertex-array gl-vertices)
(gl:draw-elements :triangles gl-indices)
........
(gl:enable-client-state :texture-coord-array)
However it leads to a memory segment address error.
If I go the primitive route, rendering the triangle vertices and texture
coordinates,
things work fine.
Obviously, as for texture coordinates with draw elements; I am missing
something. I tried
looking up into the source/examples but could not find. [PS: i am no C
expert, so am stuck here]
Any help appreciated,
Let me know in case of any questions,
Thanks and Regards,
Deepak
