[jitter] obj to mesh

August 27, 2007 | 11:34 am

Hi,

how does one use these matrices (vertex, texcoord, normal, color,
specular, edgeflag, tangent, bitangent, and index data) to make
certain that an .obj file gets intact into a jitter.mesh object ?

Theres a few example patches ive posted on the forum that deal with
morphing. You should be able to find them, and shows how with
matrixoutput 1. Take a look at the jitter opengl matrix format to
learn how to pack/unpack so you can punch the normals out from
matrixoutput 1 of jit.gl.model into jit.gl.mesh.

Thnx for replying (you are very active indeed)

On 2 july 2007 1.37 there was a mail to B.Zamborlin, where a sample
patch was included.
It shows exactly the mess i got earlier, what about the connection
matrix ?
I discovered this general morphing question arises often, but no one
mentions the ‘ connection ‘ matrix.

Appendix B of the Jittertutorial16 mentions a connection matrix.
like:
jit_matrix [geometry matrix] [connections matrix] [draw primitive].

with that matrix you can have a field of polygons where slowly a
lower poly count object arises en ‘ melts ‘ down again without
getting distorted.
