Property Descriptions

bool enable_alpha_to_coverage = false

  • void set_enable_alpha_to_coverage ( bool value )

  • bool get_enable_alpha_to_coverage ( )

If true, alpha to coverage is enabled. This generates a temporary coverage value based on the alpha component of the fragment's first color output. This allows alpha transparency to make use of multisample antialiasing.

bool enable_alpha_to_one = false

  • void set_enable_alpha_to_one ( bool value )

  • bool get_enable_alpha_to_one ( )

If true, alpha is forced to either 0.0 or 1.0. This allows hardening the edges of antialiased alpha transparencies. Only relevant if enable_alpha_to_coverage is true.

bool enable_sample_shading = false

  • void set_enable_sample_shading ( bool value )

  • bool get_enable_sample_shading ( )

If true, enables per-sample shading which replaces MSAA by SSAA. This provides higher quality antialiasing that works with transparent (alpha scissor) edges. This has a very high performance cost. See also min_sample_shading. See the per-sample shading Vulkan documentation for more details.

float min_sample_shading = 0.0

  • void set_min_sample_shading ( float value )

  • float get_min_sample_shading ( )

The multiplier of sample_count that determines how many samples are performed for each fragment. Must be between 0.0 and 1.0 (inclusive). Only effective if enable_sample_shading is true. If min_sample_shading is 1.0, fragment invocation must only read from the coverage index sample. Tile image access must not be used if enable_sample_shading is not 1.0.

TextureSamples sample_count = 0

The number of MSAA samples (or SSAA samples if enable_sample_shading is true) to perform. Higher values result in better antialiasing, at the cost of performance.

int[] sample_masks = []

  • void set_sample_masks ( int[] value )

  • int[] get_sample_masks ( )

The sample mask array. See the sample mask Vulkan documentation for more details.
