component_mem_size()

uint32_t blender::gpu::Std430::component_mem_size ( const shader::Type type )

static

Get the memory size in bytes of a single component using by the given type.

Definition at line 17 of file vk_memory_layout.cc.

element_alignment()

uint32_t blender::gpu::Std430::element_alignment ( const shader::Type type, bool is_array )

static

Get to alignment of the given type in bytes.

element_components_len()

uint32_t blender::gpu::Std430::element_components_len ( const shader::Type type )

static

Get the number of components that should be allocated for the given type.

Definition at line 49 of file vk_memory_layout.cc.

inner_row_padding()

uint32_t blender::gpu::Std430::inner_row_padding ( const shader::Type type )

static

After how many input values do we expect row padding.

Mat3 in Std430 needs to be padded so every row would contain 4 floats. inner_row_padding would contain 3 in this case, otherwise this is set to 0.
