Struct webgl_stdweb::WEBGL_color_buffer_float

pub struct WEBGL_color_buffer_float(_);

Extension

Adds support for rendering to 32-bit floating-point color buffers.

The 32-bit floating-point type RGBA32F becomes available as a color-renderable format. Renderbuffers can be created in this format. These and textures created with format = RGBA and type = FLOAT as specified in OES_texture_float, can be attached to framebuffer object color attachments for rendering.

The 32-bit floating-point type RGB32F may also optionally become available as a color-renderable format. These and textures created with format = RGB and type = FLOAT as specified in OES_texture_float, can be attached to framebuffer object color attachments for rendering. Applications must check framebuffer completeness to determine if an implementation actually supports this format.

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.

fn as_ref(&self) -> &Reference

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for WEBGL_color_buffer_float

fn clone(&self) -> WEBGL_color_buffer_float

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Extension for WEBGL_color_buffer_float

const NAME: &'static str = "WEBGL_color_buffer_float"

impl From<WEBGL_color_buffer_float> for Reference

fn from(value: WEBGL_color_buffer_float) -> Self

Converts to this type from the input type.

impl InstanceOf for WEBGL_color_buffer_float

fn instance_of(_reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl ReferenceType for WEBGL_color_buffer_float

unsafe fn from_reference_unchecked(reference: Reference) -> Self

Converts a given reference into a concrete reference-like wrapper. Doesn’t do any type checking; highly unsafe to use!
