◆ allocatePages()

std::vector< Page > tt::PipelineImage::DeviceShared::allocatePages ( int const nrPages )

noexcept

Allocate pages from the atlas.

void tt::PipelineImage::DeviceShared::destroy ( GUIDevice * vulkanDevice )

Deallocate vulkan resources. This is called in the destructor of GUIDevice_vulkan, therefor we can not use our std::weak_ptr<GUIDevice_vulkan> device.

void tt::PipelineImage::DeviceShared::freePages ( std::vector< Page > const & pages )

noexcept

Deallocate pages back to the atlas.

static ivec tt::PipelineImage::DeviceShared::getAtlasPositionFromPage ( Page page )

inlinestaticnoexcept

Get the coordinate in the atlas from a page index.

Parameters

page	number in the atlas

Returns: x, y pixel coordinate in an atlasTexture and z the atlasTextureIndex.

Image tt::PipelineImage::DeviceShared::makeImage ( ivec extent )

noexcept

Allocate an image in the atlas.

Parameters

extent of the image.
