Detailed Description

Framebuffer attachment state.

Handles the attachment state for a framebuffer that combines multiple textures and renderbuffers into one render context.

Inherits GPUresource so it's possible to add the framebuffer constructs into resource manager and have them be invalidated.

Framebuffer class is intended for internal use by other Kanzi subsystems controlling rendering. It can also be used manually:

    // Create two individual render target textures.
    Texture::CreateInfoNode2DRenderTarget createInfo1(512, 384, GraphicsFormatR8G8B8A8_UNORM);
    Texture::CreateInfoNode2DRenderTarget createInfo2(512, 384, GraphicsFormatR8_UNORM);
    TextureSharedPtr texture1 = Texture::create(domain, createInfo1, "color target 1");
    TextureSharedPtr texture2 = Texture::create(domain, createInfo2, "color target 2");
    // Create a framebuffer.
    FramebufferSharedPtr framebuffer = Framebuffer::create(domain, "framebuffer");
    // Set the textures into the color attachments.
    framebuffer->updateColorAttachment(0u, texture1);
    framebuffer->updateColorAttachment(1u, texture2);
    // Recreate the framebuffer based on the state.
    framebuffer->recreateFramebuffer(*renderer);
    // Bind framebuffer for rendering.
    // Note that since there are two color targets, the color target count must be updated.
    renderer->bindFramebuffer(framebuffer->getNativeHandle());
    renderer->setColorBufferCount(framebuffer->getDrawBufferCount());
    // After rendering, restore the color buffer count to 1 if necessary.
    renderer->bindFramebuffer(0u);
    renderer->setColorBufferCount(1u);
