This is how I added an image instead of color in RenderBox

Question

1. Copy the HelloARVideo/VideoRenderer to RenderBox(change the class name etc..)
2. Add GLKIt : #import <GLKit/GLKit.h>
3. Add a GLKTextureInfo to implementation:   GLKTextureInfo *textureInfo;
4. Remove the texture_id code and add:

   •     NSString *path = [[NSBundle mainBundle]pathForResource:@"argame00" ofType:@"jpg"];

         textureInfo = [GLKTextureLoader textureWithContentsOfFile:path options:nil error:nil];

         glBindTexture(GL_TEXTURE_2D, textureInfo.name);

5. Replace the texture_id in the render function:

   • glBindTexture(GL_TEXTURE_2D, textureInfo.name);
