I have a 3D Model (OpenGL ES 1.1 iPhone SDK v3.0) that is somewhat complex (i.e. Thousands of Vertexes and Faces) and I'd like to rotate this model around the Y-axis at or near the center of the Model. The problem is that glRotate rotates my model around a point at/near the center of one of its bottom edges, NOT near the center of the Mo...
Hi, I need to access the X,Y values of a vertex object after Ive rotated it (with glRotate3f). How is it possible? I need em to solve an object collision problem where collisions will be sending objects in an angle related direction based upon objects rotation degrees. edit:: Ok, Ive come close to find a way. Lets assume X and Y and d...
Hi, As I have understood, it is recommended to use glTranslate / glRotate in favour of glutLootAt. I am not going to seek the reasons beyond the obvious HW vs SW computation mode, but just go with the wave. However, this is giving me some headaches as I do not exactly know how to efficiently stop the camera from breaking through walls. ...
Hi guys! I´m trying to rotate a sprite using drawtexture but nothing happens. I´m using the following code: gl.glRotatef(90, 0, 0, 1.0f); gl.glBindTexture(GL10.GL_TEXTURE_2D, TextureID); (GL11Ext) gl).glDrawTexfOES(x, y, z, width, height); The texture is drawn to the screen but it is not rotated... Anyone? :) ...
