How is a 2D texture array represented in Direct3D 11?
A 2D texture array is also represented by the ID3D11Texture2D interface. It has a similar layout as the 1D texture array except that the textures now contain 2D data, as shown in the following illustration.
Which is the sample method in Texture2D?
Samples a Texture2D. Samples a texture. Samples a texture with an optional value to clamp sample level-of-detail (LOD) values to. Samples a texture with an optional value to clamp sample level-of-detail (LOD) values to, and returns status of the operation. Refer to Texture-Object.
What does a 2D texture array resource look like?
A fully populated 2D texture resource looks like the following illustration. This texture resource contains a single 3×5 texture with three mipmap levels. A 2D texture array resource is a homogeneous array of 2D textures; that is, each texture has the same data format and dimensions (including mipmap levels).
How are levels of detail represented in Direct3D 11?
The levels are identified by an index called a LOD (level-of-detail) which is used to access the smaller texture when rendering geometry that is not as close to the camera. Direct3D 11 also supports arrays of textures. A 1D texture array is also represented by the ID3D11Texture1D interface.
How is a 3D texture bound as a render target?
When a 3D texture mipmap slice is bound as a render target output (with a render-target view), the 3D texture behaves identically to a 2D texture array with n slices. The particular render slice is chosen from the geometry-shader stage, by declaring a scalar component of output data as the SV_RenderTargetArrayIndex system-value.
Can you draw a triangle in Direct3D 11?
This tutorial aims to get you set up with a minimal Direct3D 11 program that displays 1 triangle. If you can draw 1 triangle then you can draw anything. For clarity no structure or framework is used or introduced. Direct3D 11 comes in the Windows SDK. You no longer need to download any separate D3D libraries.
