Constructor Details

VulkanCaps

public VulkanCaps(ContextOptions options,
 org.lwjgl.vulkan.VkPhysicalDevice physDev,
 int physicalDeviceVersion,
 org.lwjgl.vulkan.VkPhysicalDeviceFeatures2 deviceFeatures2,
 org.lwjgl.vulkan.VKCapabilitiesInstance capabilitiesInstance,
 org.lwjgl.vulkan.VKCapabilitiesDevice capabilitiesDevice)

Method Details

hasUnifiedMemory

public boolean hasUnifiedMemory()

isFormatTexturable

public boolean isFormatTexturable(BackendFormat format)

Description copied from class: Caps

Can a texture be made with the BackendFormat, and then be bound and sampled in a shader. It must be a color format, you cannot pass a stencil format here.

For OpenGL: Formats that deprecated in core profile are not supported; Compressed formats from extensions are uncertain; Others are always supported.

Specified by:

isFormatTexturable in class Caps

getMaxRenderTargetSampleCount

public int getMaxRenderTargetSampleCount(BackendFormat format)

Description copied from class: Caps

Returns the maximum supported sample count for a format. 0 means the format is not renderable 1 means the format is renderable but doesn't support MSAA.

Specified by:

getMaxRenderTargetSampleCount in class Caps

isFormatRenderable

public boolean isFormatRenderable(int colorType,
 BackendFormat format,
 int sampleCount)

Specified by:

isFormatRenderable in class Caps

isFormatRenderable

public boolean isFormatRenderable(BackendFormat format,
 int sampleCount)

Specified by:

isFormatRenderable in class Caps

getRenderTargetSampleCount

public int getRenderTargetSampleCount(int sampleCount,
 BackendFormat format)

Description copied from class: Caps

Find a sample count greater than or equal to the requested count which is supported for a render target of the given format or 0 if no such sample count is supported. If the requested sample count is 1 then 1 will be returned if non-MSAA rendering is supported, otherwise 0.

Specified by:

getRenderTargetSampleCount in class Caps

Parameters:

sampleCount - requested samples

getSupportedWriteColorType

public long getSupportedWriteColorType(int dstColorType,
 ImageDesc dstDesc,
 int srcColorType)

Description copied from class: Caps

Given a dst pixel config and a src color type what color type must the caller coax the data into in order to use writePixels().

Low 32bits - colorType ((int) value). High 32bits - transferOffsetAlignment (value >>> 32). If the write is occurring using transferPixelsTo() then this provides the minimum alignment of the offset into the transfer buffer.

Specified by:

getSupportedWriteColorType in class Caps

onSupportedReadColorType

protected long onSupportedReadColorType(int srcColorType,
 BackendFormat srcFormat,
 int dstColorType)

Specified by:

onSupportedReadColorType in class Caps

onFormatCompatible

protected boolean onFormatCompatible(int colorType,
 BackendFormat format)

Specified by:

onFormatCompatible in class Caps

getDefaultColorImageDesc

public @Nullable ImageDesc getDefaultColorImageDesc(int imageType,
 int colorType,
 int width,
 int height,
 int depthOrArraySize,

Overrides:

Parameters:
