Hello,
I started using jogl yesterday and decided to convert over a custom model format I wrote for an Android game. The actual mesh loads and displays fine, but the texture coordinates just don't seem to work.
I know that the texture coordinates are loaded into the floatbuffer because I checked them by looping through its capacity and using ".get(i)" to print out its contents, but I'm concerned something might be going wrong when I try to bind the data because I read on a forum that if you bind a texture coordinate buffer that is too big, it can cause problems (I hope this is not true, or that there is a work around).
This is the code I use to bind the texture coordinates:
int[] buffer = new int[1];
gl2.glGenBuffers(1, buffer, 0);
textureBufferIndex = buffer[0];
gl2.glBindBuffer(GL2.GL_ARRAY_BUFFER, textureBufferIndex);
gl2.glBufferData(GL2.GL_ARRAY_BUFFER, _texBuffer.capacity()*4, _texBuffer, GL2.GL_STATIC_DRAW);
error = gl2.glGetError();
if(error != gl2.GL_NO_ERROR)
{
}
And the code I use to draw the model is:
gl2.glEnableClientState(GL2.GL_TEXTURE_COORD_ARRAY);
gl2.glBindBuffer(GL2.GL_ARRAY_BUFFER, textureBufferIndex);
gl2.glTexCoordPointer(2, GL2.GL_FLOAT, 0, 0);
gl2.glEnableClientState(GL2.GL_VERTEX_ARRAY);
gl2.glBindBuffer(GL2.GL_ARRAY_BUFFER, vertexBufferIndex);
gl2.glVertexPointer(3, GL2.GL_FLOAT, 0, 0);
gl2.glBindBuffer(GL2.GL_ELEMENT_ARRAY_BUFFER, indexBufferIndex);
gl2.glDrawElements(GL2.GL_TRIANGLES, getIndexCount(), GL2.GL_UNSIGNED_SHORT, 0);
gl2.glBindBuffer(GL2.GL_ELEMENT_ARRAY_BUFFER, 0);
gl2.glBindBuffer(GL2.GL_ARRAY_BUFFER, 0);
gl2.glDisableClientState(GL2.GL_VERTEX_ARRAY);
gl2.glDisableClientState(GL2.GL_TEXTURE_COORD_ARRAY);
No errors appear and the model renders fine, but the texturing seems all wrong, like the coordinates all sit really close to <0,0> . I'm hoping I've just made a really obvious mistake. My model's texture coordinate floatbuffer capacity is 1034, so there's 517 verticies in the model. If that is too much using this method, is there a work around?
Thanks for reading and any help would be great.
