nCine::RHI::PVR::PvrShader class

#include <nCine/Graphics/RHI/PVR/PvrShader.h>

Shader-object stub of the PVR backend.

GX is fixed-function - the backend drives TEV configurations selected from the program's label and the offline reflection instead of compiling GLSL - so this class carries no source and every operation succeeds trivially. It exists only to satisfy the RHI::Shader contract alias.

Public types

enum class Status { NotCompiled, CompilationFailed, Compiled, CompiledWithDeferredChecks }

Compilation status of the shader (always Status::Compiled for the PVR backend).

enum class ErrorChecking { Immediate, Deferred }

When the compilation status is checked (irrelevant for the PVR backend).

Constructors, destructors, conversion operators

PvrShader(std::uint32_t type) explicit

PvrShader(std::uint32_t type, StringView filename)
