WGF11 Render Targets

Note  This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.

Type: Automated Test

Overview

The WGF11RenderTargets test verifies D3D graphics driver/hardware conformance for render target features and RenderTargetViews. It also verifies driver support for render target clearing and swap chains.

Details

RenderTargets (tests mainly RenderTargetViews)

Rather than rendering to the backbuffer that is presented on the screen, you can draw to a render target resource. This is typically used in environment mapping techniques or in techniques where multiple passes are involved where the render target texture is used as input in another pass.

• Tests cycles through all formats capable of being used as a render target. No conversion takes place, but results must be within 1-ULP (Unit Least Precision) of expected result (per component).

• Three types of source data are used: tiles, gradients, and stripes. Each data type is parameterized, such as gradient colors, tile and stripe size, etc.

• Depending on the resource type (all five types are tested), the test cycles through different values for height, width, and depth. This includes non-square and non-pow-2 values.

• MRT (Multiple Render Targets) are tested, and multiple mip-levels and array slices are targeted.

• Hits all render target slots throughout the test run.

• Renders to VB, IB, and shader resource (verify in subsequent Draw() call).

• Renders to texture cube (and sub mips) by creating a Texture2DArray render target view.

Clear

Tests clearing of the bound render target view through the ClearRenderTargetView D3D API. This includes testing of the various resource types (1D, 2D, etc.), and using special floating point values as the clear value (INF, NaN, etc.).

SwapChain

Tests rendering to the backbuffer and presenting using various swap chain creation parameters, including format. Also tests back buffer casting, which is new to D3D11. This allows creating a render target view of a format that is not in the same typeless family as the resource's format.

Run Time: 40 minutes

Requirements

Software Requirements

The test tool requires the following software:

• Supported operating system (see list above)

• Software components included with the device that is being tested

Hardware Requirements

The test tool requires the following hardware:

• Device to be tested

• Computer that meets the minimum software requirements

• Windows keyboard

• Two-button pointing device

• Color display monitor capable of at least 1024 by 768 resolution, 32-bits per pixel, 60 Hz

• Hard drive with a minimum of 20 GB available on partition C:

Processor

The test tool runs on the following processor architectures:

• x86

• x64

Running the Test

All test cases return PASS or FAIL. Review the test results in the log file for specific details about failures.

The test might return SKIP if a format is not supported by the device, or if the device does not support backbuffer casting for a particular format (in the SwapChain test group).

The test might return BLOCKED if there is an uncaught exception (framework catches it at the end and logs it).
