Member Data Documentation

depth_failure

StencilOperation impeller::StencilAttachmentDescriptor::depth_failure = StencilOperation::kKeep

Indicates what to do when the stencil test passes but the depth test fails.

Definition at line 625 of file formats.h.

depth_stencil_pass

StencilOperation impeller::StencilAttachmentDescriptor::depth_stencil_pass = StencilOperation::kKeep

Indicates what to do when both the stencil and depth tests pass.

Definition at line 629 of file formats.h.

read_mask

uint32_t impeller::StencilAttachmentDescriptor::read_mask = ~0

The mask applied to the reference and stencil buffer values before performing the stencil_compare operation.

stencil_compare

CompareFunction impeller::StencilAttachmentDescriptor::stencil_compare = CompareFunction::kAlways

Indicates the operation to perform between the reference value and the value in the stencil buffer. Both values have the read_mask applied to them before performing this operation.

stencil_failure

StencilOperation impeller::StencilAttachmentDescriptor::stencil_failure = StencilOperation::kKeep

Indicates what to do when the stencil test has failed.

write_mask

uint32_t impeller::StencilAttachmentDescriptor::write_mask = ~0

The mask applied to the new stencil value before it is written into the stencil buffer.
