PEXSetBFReflectionAttributes(3) — Subroutines

Name

PEXSetBFReflectionAttributes - Set Back-Face Surface Reflection Attributes

Synopsis

void PEXSetBFReflectionAttributes(Display ∗display, XID resource_id, PEXOCRequestType req_type, PEXReflectionAttributes ∗attributes)

Arguments

displayA pointer to a display structure returned by a successful XOpenDisplay call.

resource_idThe resource identifier of the renderer or structure.

req_typeThe request type for the output command (PEXOCRender, PEXOCStore, PEXOCRenderSingle or PEXOCStoreSingle).

attributesThe back-facing surface reflection attributes.

Returns

None

Description

This function creates an output primitive attribute which sets the back-facing surface reflection attributes. Surface reflection attributes consist of the ambient, diffuse and specular coefficients, the specular concentration and color, and the transmission coefficient.
