Header: epok.hpp
Overloads: 1

Declaration

bool camera_project(const Fixed* world_point,Fixed* screen_xy)

Performs `camera project` as part of the epok module.

Parameter	Type	Meaning
`world_point`	`const Fixed *`	Value supplied for world_point. Keep referenced or pointed-to data valid for the complete call.
`screen_xy`	`Fixed *`	Value supplied for screen_xy. 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 "epok.hpp"

// Assume these named values have been initialized with valid data:
// const Fixed * world_point
// Fixed * screen_xy

auto result = epok::camera_project(world_point, screen_xy);

Why use it

The boolean result makes success, availability or state explicit without exceptions.

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.

Declared in runtime/epok.hpp:202
