Passes can render to a buffer (Render to Texture), to several buffers (Multiple Render Targets) or directly to the framebuffer. This is accomplished by the <code><attachment/></code> tag.

There are specific pass types, each with their own set of custom parameters: | |||
==== scene ==== | |||
Renders the scene from the point of view given by the CameraGroup. | |||
; cull-mask | |||
: A 32 bit number that specifies the cull mask to be used. See <tt>simgear/scene/util/RenderConstants.hxx</tt> to know which bits enable what. | |||
; z-near and z-far | |||
: They change the depth range to be used. If both of them are zero, the default Z range in the CameraGroup is used. | |||
; clustered-forward | |||
: Enables the use of clustered forward rendering for this pass. | |||
; cubemap-face | |||
: Ignores the given view and projection matrices and uses a custom one that renders the scene as if it was seen from inside a cubemap looking towards the specified face. | |||
==== quad ==== | |||
Renders a fullscreen quad with an optional [[Effects|effect]] applied. Useful for screen space shaders (like SSAO, Screen Space Reflections or bloom) and deferred rendering. | |||
; geometry | |||
: Specifies the x, y, width and height of the fullscreen quad inside the viewport using normalized coordinates. | |||
; effect | |||
: The quad will use this effect. | |||
==== shadow-map ==== | |||
Renders the scene from a light's point of view. | |||
; light-num | |||
: The OpenGL light number to use for this shadow map. | |||
; near-m and far-m | |||
: They specify the range of the shadow map. | |||
