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.

Stability:	Unstable
Available since:	1.10

Parameters

`fov_y`	`float`
	Vertical field of view angle in degrees.
`aspect`	`float`
	The (width over height) aspect ratio for display.
`z_near`	`float`
	The distance to the near clipping plane (Must be positive, and must not be 0)
`z_far`	`float`
	The distance to the far clipping plane (Must be positive)
