Struct GlTexture 

pub struct GlTexture { /* private fields */ }

Implementations

impl GlTexture

pub fn new( server: &GlGraphicsServer, desc: GpuTextureDescriptor<'_>, ) -> Result<GlTexture, FrameworkError>

Creates new GPU texture of specified kind. Mip count must be at least 1, it means that there is only main level of detail.

Data layout

In case of Cube texture, bytes should contain all 6 cube faces ordered like so, +X, -X, +Y, -Y, +Z, -Z. Cube mips must follow one after another.

Produced texture can be used as render target for framebuffer, in this case data parameter can be None.

Compressed textures

For compressed textures data must contain all mips, where each mip must be 2 times smaller than previous.

pub fn bind(&self, server: &GlGraphicsServer, sampler_index: u32)

pub fn id(&self) -> <Context as HasContext>::Texture

Trait Implementations

impl Drop for GlTexture

fn drop(&mut self)

Executes the destructor for this type.

impl GpuTextureTrait for GlTexture

fn set_data( &self, kind: GpuTextureKind, pixel_kind: PixelKind, mip_count: usize, data: Option<&[u8]>, ) -> Result<usize, FrameworkError>

Sets the new data of the texture. This method is also able to change the kind of the texture and its pixel kind. Returns the number of bytes occupied by the texture in the video memory. If there’s no data specified, the texture will still take the space defined by its metrics.

fn kind(&self) -> GpuTextureKind

Returns kind of the texture.

fn pixel_kind(&self) -> PixelKind

Returns pixel kind of the texture.
