inline bool project_geometry_triple(const int16_t (*vertices)[3],const int32_t* offset, uint32_t* screen,int32_t* depth)Interior retained chunks never need camera X/Y for software clipping.
| Parameter | Type | Meaning |
|---|---|---|
vertices | const int16_t (*)[3] | Value supplied for vertices. Keep referenced or pointed-to data valid for the complete call. |
offset | const int32_t * | Value supplied for offset. Keep referenced or pointed-to data valid for the complete call. |
screen | uint32_t * | Value supplied for screen. Keep referenced or pointed-to data valid for the complete call. |
depth | int32_t * | Value supplied for depth. Keep referenced or pointed-to data valid for the complete call. |
Returns: bool. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "gte_geometry.hpp"
// Assume these named values have been initialized with valid data:
// const int16_t (*)[3] vertices
// const int32_t * offset
// uint32_t * screen
// int32_t * depth
auto result = epok::project_geometry_triple(vertices, offset, screen, depth);Trade-offs and warnings
Check the return value; `false` is part of normal control flow for many PSX resource operations. Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
