Okay here is what i am trying to do… is i am trying to make my own gltranslate function basically with out conventionally glMultMatrixf or glLoadMatrix… so i decided to do a little research and here is what i came up with… that if you group objects to move the same ( i call it clustering ) then i assign it a
btw the code is all in C.
so the structure goes
cluster(contains triangles and numtriangles and [obj matrix])
triangle which contains vertexes
vertexes which contain x,y,z,u,v
so i made my own glulookat function and decided to begin from there… i got everything working for the glulookat function (my implementation) i could walk around and all, strafe movement with mouse. so now i want to really see how OpenGl works by doing this little project.
But i need some help. My algo in pseudocode:
MatrixBy= Matrix multiplying
(maybe i am doing this wrong I haven’t really looked into it. I got it off a site who offers sound advice–not a good practice, but for times sake i decided to.)
//^ not sure about this… don’t think i need it
MatrixBy( T, cluster.objmatrix, res );
MatrixBy( res, m, res );
and then for each vertex i multiply it by a triangle vertex…
sector1.triangle[triloop].vertex = MatrixbyVertex(res,sector1.triangle[triloop].vertex);
then i draw each triangle in a loop if you want my code just request it.
Thanks for listening,
