GPU Support
GPU support is currently provided by a single
glsl file.
This file can be pasted at the start of a shader to provide limited functionality supported by the
full C++ Klein library. The kln_plane, kln_line, kln_point, kln_rotor, and kln_motor entity structs defined
in this shader header are byte-for-byte identical to their C++ counterparts.
Currently, the following functions are supported:
| Function | Description |
|---|---|
kln_rotor kln_mul(in kln_rotor a, in kln_rotor b) |
Multiplies two rotors and returns the result |
kln_translator kln_mul(in kln_translator a, in kln_translator b) |
Multiplies two translators and returns the result |
kln_motor kln_mul(in kln_motor a, in kln_motor b) |
Multiplies two motors and returns the result |
kln_plane kln_apply(in kln_rotor r, in kln_plane p) |
Applies a rotor to a plane |
kln_plane kln_apply(in kln_motor m, in kln_plane p) |
Applies a motor to a plane |
kln_point kln_apply(in kln_rotor r, in kln_point p) |
Applies a rotor to a point |
kln_point kln_apply(in kln_motor m, in kln_point p) |
Applies a motor to a point |
kln_point kln_apply(in kln_motor m) |
Applies a motor to the origin |
GPU support is verified with a C++ test suite powered by a shim to handle vector swizzle operations and provide implementations for GLSL built-in functions. GPU support is currently preliminary and achieving parity with seamless interoperability with the Klein C++ headers is an ongoing objective.
