Thanks so much :)

It works fine!!!!

I got the castle from here http://www.turbosquid.com/FullPreview/Index.cfm/ID/552087

It's a good resource. I had to flip the texture to get it to work properly.

HI,

Please, can you send me the castle .obj and its flat texture .jpg to test my app. My email is

. Thanks in advance. :)

That is also correct although it doesn't fix the issues described above for me.

I don't know if this will help you guys, but I resized my texture to 256x256 and it worked perfectly, the dimensions probably need to be multiple of 2, like: 32x32, 64x64, 128x128... I'm just guessing, can anyone confirm it?

As I said. Once I had the banana showing I tried to load my castle model. The texture was incorrect but was fixed by flipping the texture vertically.

Hi, garyriches:)
I have a same problem with you like a banana.
So I just use one colored texture.
How to do the mapping of the castle, it's awesome for me.
Can you give me a hint, plz~

Thanks MoSR, having broken down the texture in to coloured quads everything seems to be ok. I had already flipped the banana skin and it didn't look perfect. I then tried loading my castle model and flipped that texture and low and behold... it worked!

I have since come to the conclusion that maybe the banana isn't textured 100% correctly, can anyone confirm this?

Here are the results

Try using a texture with 4 different coloured quadrants - it may help you understand where the texture coordinate mapping is wrong.

Thanks I tried that and whilst the opposite half looked better the other half (that used to look ok-ish) looked worse.

I have also loaded a 3d castle model and the texture doesn't seem to it correctly on that either. It's a flat texture, 1024 x 1024.

I resized the texture down to that from 4000 x 4000. I checked if I needed to regenerate the texture coords but it seemed I didn't.

Is there some way of specifying different types of mapping?

Try flipping the texture image vertically.

Ok, so I managed to display the banana using:

[PHP" /> glVertexAttribPointer(vertexHandle, 3, GL_FLOAT, GL_FALSE, 0, (const GLvoid*) &bananaVerts[0" />);

glVertexAttribPointer(normalHandle, 3, GL_FLOAT, GL_FALSE, 0,
(const GLvoid*) &bananaNormals[0" />);

glVertexAttribPointer(textureCoordHandle, 2, GL_FLOAT, GL_FALSE, 0,
(const GLvoid*) &bananaTexCoords[0" />);

glEnableVertexAttribArray(vertexHandle);
glEnableVertexAttribArray(normalHandle);
glEnableVertexAttribArray(textureCoordHandle);

glActiveTexture(GL_TEXTURE0);
glBindTexture(GL_TEXTURE_2D, [thisTexture textureID" />);

glUniformMatrix4fv(mvpMatrixHandle, 1, GL_FALSE,
(GLfloat*)&modelViewProjection.data[0" /> );

glDrawArrays(GL_TRIANGLES, 0, bananaNumVerts);[/PHP" />

The key was setting kObjectScale to 150 as the banana was showing, but too small to actually see.

The issue I have now is the texture mapping is wrong, it doesn't fit to the banana.

A screen shot is here

My EAGLView.mm is here

Any ideas why?
