Method
CoglFramebufferperspective
Declaration [src]
void
cogl_framebuffer_perspective (
  CoglFramebuffer* framebuffer,
  float fov_y,
  float aspect,
  float z_near,
  float z_far
)
Description [src]
Replaces the current projection matrix with a perspective matrix based on the provided values.
You should be careful not to have to great a z_far / z_near
ratio since that will reduce the effectiveness of depth testing
since there won’t be enough precision to identify the depth of
objects near to each other.
Parameters
- fov_y
- 
            Type: floatVertical field of view angle in degrees. 
- aspect
- 
            Type: floatThe (width over height) aspect ratio for display. 
- z_near
- 
            Type: floatThe distance to the near clipping plane (Must be positive, and must not be 0). 
- z_far
- 
            Type: floatThe distance to the far clipping plane (Must be positive).
