Why use it
Template dispatch is resolved at compile time and normally adds no runtime indirection.

epok::frustum_outcode32
Function template · 1 overload
Function template
Plain 32-bit variant for inputs bounded by 2^27 in magnitude (the GTE projection path guarantees this); 3z+4y then cannot overflow.
Declaration
templateDeclaration
template<int32_t Near,int32_t FarExclusive> inline uint8_t frustum_outcode32(int32_t x,int32_t y,int32_t z)Plain 32-bit variant for inputs bounded by 2^27 in magnitude (the GTE projection path guarantees this); 3z+4y then cannot overflow.
| Parameter | Type | Meaning |
|---|---|---|
x | int32_t | Value supplied for x. Keep referenced or pointed-to data valid for the complete call. |
y | int32_t | Value supplied for y. Keep referenced or pointed-to data valid for the complete call. |
z | int32_t | Value supplied for z. Keep referenced or pointed-to data valid for the complete call. |
Returns: uint8_t. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "frustum.hpp"
// Replace these template arguments with types or values accepted by the declaration:
// Near, FarExclusive
// Assume these named values have been initialized with valid data:
// int32_t x
// int32_t y
// int32_t z
auto result = epok::frustum_outcode32<Near, FarExclusive>(x, y, z);Trade-offs and warnings
Every instantiated type must satisfy the header's compile-time requirements; extra instantiations can increase code size.
