Detailed Description

Color scale arguments as used by the graphics device or shader program.

Generalizes the mapping options of different color scale implementations to make them usable within a shader. Members must follow the alignment rules of the device and the size of the struct must be a multiple of 16 bytes, which may necessitate the use of padding.

◆ log_upper_bound

float cgv::render::device_color_scale_arguments::log_upper_bound = 1.0f

Definition at line 51 of file device_color_scale.h.

◆ mapping_options

DeviceColorScaleMappingOptions cgv::render::device_color_scale_arguments::mapping_options = DeviceColorScaleMappingOptions::kNone

Definition at line 56 of file device_color_scale.h.

◆ midpoint

float cgv::render::device_color_scale_arguments::midpoint = 0.5f

Definition at line 46 of file device_color_scale.h.

◆ sample_mode

DeviceColorScaleSampleMode cgv::render::device_color_scale_arguments::sample_mode = DeviceColorScaleSampleMode::kContinuous

Definition at line 57 of file device_color_scale.h.

◆ transform

uint16_t cgv::render::device_color_scale_arguments::transform = 0

The next three fields "transform, mapping_options and sample_mode" take up 4 bytes in total.

They have to be specified in reverse order of how they are used in the shader to account for different endianness.

◆ unknown_color

rgba8 cgv::render::device_color_scale_arguments::unknown_color = { 0, 0, 0, 255 }
