gDPSetEnvColor [macro]
Syntax
#include <ultra64.h> /* gbi.h */
gDPSetEnvColor(Gfx *gdl, u32 r, u32 g, u32 b, u32 a)
gsDPSetEnvColor(u32 r, u32 g, u32 b, u32 a)
Arguments
- gdl is the display list pointer.
- r is the red component of RGBA color (8-bit precision, 0~255).
- g is the green component of RGBA color (8-bit precision, 0~255).
- b is the blue component of RGBA color (8-bit precision, 0~255).
- a is the alpha component of RGBA color (8-bit precision, 0~255).
Explanation
Sets the RDP's environment color, which is used as an input source for linear interpolation by the color combiner (CC). The environment color register set by this macro becomes a general-purpose color register of the CC, expressing the environment color of the scene. It is also used for rendering a second specular highlight (Hilite2). The value in this environment color register determines the highlight color for Hilite2.
For details, please see Section 12.6.2, "CC Internal Color Registers," in the N64 Online Programming Manual.
