【问题描述】:
我想在 C# 上使用 directx,我正在使用 SharpDX 包装器。我得到了一本名为 Direct3D 渲染食谱的书,并从中获得了基本代码。我想创建一个 3d 世界观。为此,我将需要一个摄像机视图和一个网格,以帮助识别世界位置,就像在 Autodesk Maya 中一样,但我不知道该怎么做。我的心情很复杂,我该怎么做才能开始?
这里我有代码可以渲染我认为的东西:
using System;
using SharpDX.Windows;
using SharpDX.DXGI;
using SharpDX.Direct3D11;
using Device = SharpDX.Direct3D11.Device;
using Device1 = SharpDX.Direct3D11.Device1;
namespace CurrencyConverter
{
static class Program
{[STAThread]
static void Main()
{
// Enable object tracking
SharpDX.Configuration.EnableObjectTracking = true;
SharpDX.Animation.Timer timer = new SharpDX.Animation.Timer();
#region Direct3D Initialization
// Create the window to render to
Form1 form = new Form1();
form.Text = "D3DRendering - EmptyProject";
form.Width = 640;
form.Height = 480;
// Declare the device and swapChain vars
Device device;
SwapChain swapChain;
// Create the device and swapchain
// First create a regular D3D11 device
using (var device11 = new Device(
SharpDX.Direct3D.DriverType.Hardware,
DeviceCreationFlags.None,
new[] {
SharpDX.Direct3D.FeatureLevel.Level_11_1,
SharpDX.Direct3D.FeatureLevel.Level_11_0,
}))
{
// Query device for the Device1 interface (ID3D11Device1)
device = device11.QueryInterfaceOrNull<Device1>();
if (device == null)
throw new NotSupportedException(
"SharpDX.Direct3D11.Device1 is not supported");
}// Rather than create a new DXGI Factory we reuse the
// one that has been used internally to create the device
using (var dxgi = device.QueryInterface<SharpDX.DXGI.Device2>())
using (var adapter = dxgi.Adapter)
using (var factory = adapter.GetParent<Factory2>())
{
var desc1 = new SwapChainDescription1()
{
Width = form.ClientSize.Width,
Height = form.ClientSize.Height,
Format = Format.R8G8B8A8_UNorm,
Stereo = false,
SampleDescription = new SampleDescription(1, 0),
Usage = Usage.BackBuffer | Usage.RenderTargetOutput,
BufferCount = 1,
Scaling = Scaling.Stretch,
SwapEffect = SwapEffect.Discard,
};
swapChain = new SwapChain1(factory,
device,
form.Handle,
ref desc1,
new SwapChainFullScreenDescription()
{
RefreshRate = new Rational(60, 1),
Scaling = DisplayModeScaling.Centered,
Windowed = true
},
// Restrict output to specific Output (monitor)
adapter.Outputs[0]);
}
// Create references for backBuffer and renderTargetView
var backBuffer = Texture2D.FromSwapChain<Texture2D>(swapChain,
0);
var renderTargetView = new RenderTargetView(device,
backBuffer);
#endregion
// Setup object debug names
device.DebugName = "The Device";
swapChain.DebugName = "The SwapChain";
backBuffer.DebugName = "The Backbuffer";
renderTargetView.DebugName = "The RenderTargetView";
#region Render loop
// Create and run the render loop
RenderLoop.Run(form, () =>
{
// Clear the render target with...
var lerpColor = SharpDX.Color.Lerp(SharpDX.Color.White,
SharpDX.Color.DarkBlue,
(float)((timer.Time) / 10.0 % 1.0));
device.ImmediateContext.ClearRenderTargetView(
renderTargetView,
lerpColor);
// Execute rendering commands here...
//...
//I DO NOT HAVE ANY IDEA
//...
// Present the frame
swapChain.Present(0, PresentFlags.RestrictToOutput);
});
#endregion
#region Direct3D Cleanup
// Release the device and any other resources created
renderTargetView.Dispose();
backBuffer.Dispose();
device.Dispose();
swapChain.Dispose();
#endregion
}
}
}
