class VulkanTexture : public portal::renderer::Texture

Vulkan texture with automatic mipmap generation and sampler management.

Wraps VulkanImage with texture-specific functionality: automatic mipmap generation, CPU buffer management, sampler configuration, and texture type support (2D/cube).

Public Functions

explicit VulkanTexture(const StringId &id, const TextureProperties &properties, const Buffer &data, const VulkanContext &context)

Constructs Vulkan texture.

Parameters:

  • id – Texture ID

  • properties – Texture properties

  • data – CPU texture data

  • context – Vulkan context

virtual void resize(const glm::uvec3 &size) override

Resizes texture.

Parameters:

size – New size

virtual void resize(size_t width, size_t height, size_t depth) override

Resizes texture.

Parameters:

  • width – New width

  • height – New height

  • depth – New depth

void update_image()

Updates GPU image from CPU buffer.

void set_sampler(const Reference<Sampler> &sampler)

Sets texture sampler.

Parameters:

sampler – Sampler to use

virtual ImageFormat get_format() const override

Gets texture format.
