Struct webgl_stdweb::EXT_color_buffer_half_float

pub struct EXT_color_buffer_half_float(_);

Extension

All references to R16F and RG16F types are ignored.

WebGL implementations supporting this extension are required to support rendering to RGBA16F format.

The 16-bit floating-point types RGB16F and RGBA16F become available as color-renderable formats. Renderbuffers can be created in these formats. These and textures created with type = HALF_FLOAT_OES, which will have one of these internal formats, can be attached to framebuffer object color attachments for rendering. Implementations supporting this extension are required to support rendering to RGBA16F format. Applications must check framebuffer completeness to determine if RGB16F is supported.

NOTE: fragment shaders outputs gl_FragColor and gl_FragData[0] will only be clamped and converted when the color buffer is fixed-point and blendColor() and clearColor() will no longer clamp their parameter values on input. Clamping will be applied as necessary at draw time according to the type of color buffer in use.

The format and type combination RGBA and FLOAT becomes valid for reading from a floating-point rendering buffer. Note: RGBA and UNSIGNED_BYTE cannot be used for reading from a floating-point rendering buffer.

The component types of framebuffer object attachments can be queried.

impl Extension for EXT_color_buffer_half_float

const NAME: &'static str = "EXT_color_buffer_half_float"

impl From<EXT_color_buffer_half_float> for Reference

fn from(value: EXT_color_buffer_half_float) -> Self

Converts to this type from the input type.

impl InstanceOf for EXT_color_buffer_half_float

fn instance_of(_reference: &Reference) -> bool
