I don't think anything is wrong with my structure holding my information about the model. Why do I think this? Well, I have written a basic 3d model loader in OpenGL that loads various file formats such as 3ds, obj, asc, x, custom formats, etc. When I extract the info from the files, I can texture m...

Ok, I did a for(j=0; j<756*3; j++) { vertecies[j].u = 1.0f - vertecies[j].u; vertecies[j].v = 1.0f - vertecies[j].v; } And I can tell that the model is VERY VERY close to being texture properly because now I can actually see some of the textures coming together however the model still isn't texture ...

So I should do both

u = 1.0f - u;

v = 1.0f - v;

or just

v = 1.0f - v;

Hey thanks TIM! I did try Ector's tool and it brought me closer to getting it to work. At least my texture shows up correctly but it isn't being mapped properly still.

Hey Tim! Thanks for your help thus far. You have really tried to help me and I appreciate that.

Can someone please convert my texture to a 32-bit or a 16-bit ABGR RAW format texture so that I can see if there is a problem with my code or my image software. The link to the texture is here.

Texture Mapping with the Gu Lib

Hi! I am trying to texture map my 3d object using the gulib. So far, I can see my 3d model. it renders fine. However If I try to add a texture to it, the texture turns to a pink color and is distorted but the model still stays in tact. I modified the samples/gu/cube example. I have a model with 756 ...

Rotation Math Question

Hey everyone. I have a simple math question for you. I know how to rotate a point about the origin by using matricies. I also know how to do it using the formula. The way I do it is x = x*cos(theta) - y*sin(theta) y = x*sin(theta) + y*cos(theta) However I want to rotate my triangle about an arbitrar...

Hmmm I read the post that shine sent me about rotating triangles and their properties. I have a question though. Why does the author of the code choose to use a shift operation for the indicies of his array of numbers in his matrix? Here is an example of his code void matrix_identity&#40;float* ...
