Member Enumeration Documentation

bit_flags

enum fastuidraw::gpu_dirty_state::bit_flags

Enumeration to specify the bit-flags to specify dirty GPU state.

Enumerator
shader	If this bit is up, indicates that the shaders used by the GPU has changed.
textures	If this bit is up, indicates that the binding of the texture binding slots used by the shader of a PainterBackend derived class have changed. For example, in GL these changes are accompished by calling glBindTexture().
images	If this bit is up, indicates that the binding of the image binding slots used by the shader of a PainterBackend derived class have changed. For example, in GL these changes are accompished by calling glBindImageTexture().
blend_mode	If this bit is up, indicates that the blend state of the GPU has changed.
render_target	If this bit is up, indicates that the bound render-target of the GPU has changed. For example, in GL changing the render-target is accomplished by glBindFramgebuffer() and/or glDrawBuffers().
viewport_scissor	If this bit is up, indicates that the viewport or scissor values have changed. For example, in GL this is accomplished by calling glViewport(), glScissor() or glEnable/glDisable() passing GL_SCISSOR_TEST.
vertex_index_source	If this bit is up, indicates that the source or format for index or vertex buffers has changed. For example, in GL, this can be accomplished by calling glBindVertexArray() or modifying the currently bound vertex array object.
constant_buffers	If this bit is up, indicates that a constant buffer source has changed. For GL, these are UBOs. For example, in GL, this can be accomplished by calling glBindBuffer() with the binding target as GL_UNIFORM_BUFFER.
storage_buffers	If this bit is up, indicates that a storage buffer source has changed. For GL, these are UBOs. For example, in GL, this can be accomplished by calling glBindBuffer() with the binding target as GL_SHADER_STORAGE_BUFFER.
depth_stencil	If this bit is up, the depth or stencil test has been modified.
buffer_masks	If this bit is up, the color, depth or stencil masks have changed. For example, in GL this is accomlished by called glColorMask() glDepthMask() or glStencilMask().
hw_clip	If this bit is up, indicates that the HW clip planes has changed.
all	Specify that all state is dirty.
