Magnum::GL::CubeMapTextureArray class

Cube map texture array.

See CubeMapTexture documentation for introduction.

Usage

See Texture documentation for introduction.

Common usage is to specify each layer and face separately using setSubImage(). You have to allocate the memory for all layers and faces first by calling setStorage(). Example: array with 4 layers of cube maps, each cube map consisting of six 64x64 images, i.e. 24 layers total:

GL::CubeMapTextureArray texture;
texture.setMagnificationFilter(GL::SamplerFilter::Linear)
    // ...
    .setStorage(Math::log2(64)+1, GL::TextureFormat::RGBA8, {64, 64, 24});

for(std::size_t i = 0; i != 4; i += 6) {
    ImageView3D imagePositiveX(PixelFormat::RGBA8Unorm, {64, 64, 1}, data);
    // ...
    texture.setSubImage(0, Vector3i::zAxis(i+0), imagePositiveX);
    texture.setSubImage(0, Vector3i::zAxis(i+1), imageNegativeX);
    texture.setSubImage(0, Vector3i::zAxis(i+2), imagePositiveY);
    // ...
}

texture.generateMipmap();

In shader, the texture is used via samplerCubeArray, samplerCubeArrayShadow, isamplerCubeArray or usamplerCubeArray. Unlike in classic textures, coordinates for cube map texture arrays is signed four-part vector. First three parts define vector from the center of the cube which intersects with one of the six sides of the cube map, fourth part is layer in the array. See AbstractShaderProgram for more information about usage in shaders.

Function documentation

static Vector3i Magnum::GL::CubeMapTextureArray::maxSize()

Max supported size of one side of cube map texture array.

The result is cached, repeated queries don't result in repeated OpenGL calls. If ARB_texture_cube_map_array (part of OpenGL 4.0) is not available, returns zero vector.

static Vector2i Magnum::GL::CubeMapTextureArray::compressedBlockSize(TextureFormat format)

Compressed block size.

See Texture::compressedBlockSize() for more information.

static Int Magnum::GL::CubeMapTextureArray::compressedBlockDataSize(TextureFormat format)

Compressed block data size.

See Texture::compressedBlockDataSize() for more information.

static CubeMapTextureArray Magnum::GL::CubeMapTextureArray::wrap(GLuint id, ObjectFlags flags = {})

Wrap existing OpenGL cube map array texture object.

Parameters
id OpenGL cube map array texture ID
flags Object creation flags

The id is expected to be of an existing OpenGL texture object with target GL_TEXTURE_CUBE_MAP_ARRAY. Unlike texture created using constructor, the OpenGL object is by default not deleted on destruction, use flags for different behavior.

Magnum::GL::CubeMapTextureArray::CubeMapTextureArray() explicit

Constructor.

Creates new OpenGL texture object. If ARB_direct_state_access (part of OpenGL 4.5) is not available, the texture is created on first use.

Magnum::GL::CubeMapTextureArray::CubeMapTextureArray(NoCreateT) explicit noexcept

Construct without creating the underlying OpenGL object.

The constructed instance is equivalent to moved-from state. Useful in cases where you will overwrite the instance later anyway. Move another object over it to make it useful.

This function can be safely used for constructing (and later destructing) objects even without any OpenGL context being active.

void Magnum::GL::CubeMapTextureArray::bindImage(Int imageUnit, Int level, Int layer, ImageAccess access, ImageFormat format)

Bind level of given texture layer to given image unit.

Parameters
imageUnit Image unit
level Texture level
layer Texture layer
access Image access
format Image format

Layer is equivalent to layer * 6 + number of texture face, i.e. +X is 0 and so on, in order of (+X, -X, +Y, -Y, +Z, -Z).

void Magnum::GL::CubeMapTextureArray::bindImageLayered(Int imageUnit, Int level, ImageAccess access, ImageFormat format)
