Detailed Description

Low-level API providing access to GPU.

Used internally.

Typedef Documentation

handle_t

typedef unsigned int Beatmup::GL::handle_t

A reference to a GPU resource.

Definition at line 61 of file basic_types.h.

Enumeration Type Documentation

Extensions

enum Beatmup::GL::Extensions

Supported OpenGL estensions.

Used to communicate to a shader/program specific extensions used in the GLSL code. This defines Beatmup GLSL dialect interpretation.

Enumerator
NONE	no extension
BEATMUP_DIALECT	pseudo-extension enabling Beatmup GLSL dialect
EXTERNAL_TEXTURE	GL_OES_EGL_image_external_essl3 if available or GL_OES_EGL_image_external.

Definition at line 63 of file program.h.

                        {
            NONE = 0,                       //!< no extension
            BEATMUP_DIALECT = 1 << 0,       //!< pseudo-extension enabling Beatmup GLSL dialect
            EXTERNAL_TEXTURE = 1 << 1       //!< GL_OES_EGL_image_external_essl3 if available or GL_OES_EGL_image_external
        };
