What's the replacement for new_texture_no_texels? about luminance-rs HOT 5 CLOSED

TexelUpload::reserve in luminance 0.46 is working for what I needed.

from luminance-rs.

Yeah, seems like an oversight in the new API. It should be easy to add another option to TexelUpload.

from luminance-rs.

TexelUpload::base_level_with_mipmaps(&[], mipmaps),

Is what is currently being used. A missing bit of documentation, I guess.

from luminance-rs.

That doesn't seem to work. For example, if I modify my code to

        let texture = context.new_texture(
            layout.dimensions(),  // [256, 256, 256]
            Sampler {
                wrap_s: Wrap::ClampToEdge,
                wrap_t: Wrap::ClampToEdge,
                wrap_r: Wrap::ClampToEdge,
                mag_filter: MagFilter::Nearest,
                min_filter: MinFilter::Nearest,
                ..Sampler::default()
            },
            TexelUpload::base_level_with_mipmaps(&[], 0),
        )?;

then I get the runtime error NotEnoughPixels { expected_bytes: 67108864, provided_bytes: 0 }.

Ah, I see a possible misunderstanding. I want to create a texture of a specific nonzero size so that I can later write to parts of it (in texture atlas fashion) using upload_part(), and that used to work. Uploading 64 MiB of dummy pixels can take around 100 ms on the WebGL backend in Chrome, and I'd like to avoid a frame hiccup that large in the event I need to resize the atlas.

Yep, I reproduce with mrt example. Thanks for noticing.
