Enumeration Type Documentation

NativeCommandType

enum class LLGL::OpenGL::NativeCommandType

strong

Enumeration of all native commands the OpenGL backend can execute.

NativeCommand::type

Enumerator

ClearCache

Clears the internal command buffer cache. Remarks This should be used when a native command buffer handle is retrieved and LLGL is supposed to continue dispatching graphics and compute commands after the native command buffer has been modified. This is a slow operation because all internally managed OpenGL states will be retrieved from the current GL context, i.e. a large number of glGet* functions will be invoked by this operation.

RenderSystemNativeType

enum class LLGL::OpenGL::RenderSystemNativeType

strong

Native type enumeration for the OpenGL render system to distinguish between GLX (X11) and EGL (Wayland).

ResourceNativeType

enum class LLGL::OpenGL::ResourceNativeType

strong

Native OpenGL resource type enumeration.

Enumerator
Buffer	Default buffer resource. Remarks Its identifier was created with glGenBuffers.
Texture	Default texture resource. Remarks Its identifier was created with glGenTextures.
Sampler	Sampler-state resource. Remarks Its identifier was created with glGenSamplers if the OpenGL extension GL_ARB_sampler_objects is available.
Renderbuffer	Default renderbuffer resource. Remarks Its identifier was created with glGenRenderbuffers. This is used for depth-stencil textures that cannot be read or written directly by shaders.
ImmutableBuffer	Immutable buffer resource. Remarks Its identifier was created with glCreateBuffers if the OpenGL extension GL_ARB_direct_state_access is available.
ImmutableTexture	Immutable texture resource. Remarks Its identifier was created with glCreateTextures if the OpenGL extension GL_ARB_direct_state_access is available.
ImmutableRenderbuffer	Immutable renderbuffer resource. Remarks Its identifier was created with glCreateRenderbuffers if the OpenGL extension GL_ARB_direct_state_access is available. This is used for depth-stencil textures that cannot be read or written directly by shaders.
EmulatedSampler	Emulated sampler-state resource. Remarks This does not provide an identifier and is only used when the OpenGL extension GL_ARB_sampler_objects is not available.
