改进和变更

公共API和向后不兼容的更改

这个版本有两个主要的API变化:

  • 重构了动画系统，因此我们可以保留一些名称，以备将来支持CAD格式时使用。 -这个版本重新命名曲线到关键框架序列,以及曲线映射到绑定点。过时的接口将从Aspose.3D for .NET 20.03中删除。使用这些类的方法将提供替代方案。 -虽然旧名称仍然存在于19.12中，但依赖于这些更改的代码需要更少甚至不需要更改 (如果您使用类型推断)。
  • 删除了旧版OpenGL渲染器，并重构了渲染器，使其与基础Vulkan驱动程序配合得最好。低级接口已更改，同时保持高级渲染接口完好无损。 -重构渲染器具有更好的渲染性能，具有更大的灵活性和可扩展性。 -中的渲染方法场景班级没有变化。如果您使用高级渲染界面，则无需更改任何内容。 -低级API发生了重大变化，您可能需要与支持人员联系以进行代码迁移。

以下是有关此版本中公共API更改的详细信息。

  • 重命名类Aspose.ThreeD.动画.曲线到Aspose.ThreeD.动画.KeyframeSequence
  • 重命名类Aspose.ThreeD.动画.曲线映射到Aspose.ThreeD.动画.BindPoint

所有相关的方法/属性都标记为已过时，将来将被删除，并提供新的方法/属性。

成员被删除

删除类Aspose.ThreeD.渲染资源

旧渲染体系结构中最小渲染任务的基类。新的渲染器将为文件读/写设计的对象模型和渲染实现分开，因此不再需要RenderableResource。

 public ShaderProgram CreateShaderProgram(ShaderSource shaderSource, IList<VertexField> inputFields);

public ShaderProgram CreateShaderProgram(ShaderSource shaderSource, VertexDeclaration vertexDeclaration);

public RenderState CreateRenderState();

从班级中删除成员Aspose.ThreeD.Render.渲染器

这些被删除的成员是低级渲染相关的，19.12 EntityRenderer和ICommandList将负责渲染实现。

 public void BindRenderState(Aspose.ThreeD.Render.RenderState renderState)

public void DrawIndexed(Aspose.ThreeD.Render.DrawOperation drawOperation, Aspose.ThreeD.Render.IVertexBuffer vertexBuffer, Aspose.ThreeD.Render.IIndexBuffer indexBuffer, int count)

public void Draw(Aspose.ThreeD.Render.DrawOperation drawOperation, Aspose.ThreeD.Render.IVertexBuffer vertexBuffer, int first, int count)

public void Draw(Aspose.ThreeD.Render.DrawOperation drawOperation, Aspose.ThreeD.Render.IVertexBuffer vertexBuffer)

public void DrawIndexed(Aspose.ThreeD.Render.DrawOperation drawOperation, Aspose.ThreeD.Render.IVertexBuffer vertexBuffer, Aspose.ThreeD.Render.IIndexBuffer indexBuffer)

public void SubmitRenderTask(Aspose.ThreeD.Render.RenderQueueGroupId groupId, int priority, Aspose.ThreeD.Node node, Aspose.ThreeD.Render.IRenderable renderableTask)

public Aspose.ThreeD.Render.Renderer CurrentContext{ get;}
  • 去除枚举Aspose.ThreeD.Render.VariableSemantic -19.12中的渲染器将不再管理着色器变量，相反，每个实体渲染器实现将通过推送常量或统一缓冲区手动向着色器提供所需的数据，这使得渲染器更高效、更简单。
  • 从Aspose.ThreeD.Render.ShaderVariable -公共变量语义 {get;}
  • 从班级中删除成员Aspose.ThreeD.渲染.着色程序 -公共IList<Aspose.ThreeD.Render.ShaderVariable>变量 {get;set;}
  • 删除类Aspose.ThreeD.渲染资源 -旧渲染体系结构中最小渲染任务的基类。新的渲染器将为文件读/写设计的对象模型和渲染实现分开，因此不再需要RenderableResource。

添加的类

  • 添加类Aspose.ThreeD.Render.EntityRenderer -子类为指定实体提供渲染实现。
  • 添加类Aspose.ThreeD.渲染.ICommandList -子类化的EntityRenderer使用ICommandList对呈现实体的指令进行编码。
  • 添加类Aspose.ThreeD.Render.IDescriptorSet -描述符集是一组描述符，描述符可以是统一的缓冲区，纹理单元或其他GPU侧资源。如果多个实体共享相同的图形管道，但具有不同的纹理和其他数据，则它们可以使用IDescriptorSet来提供每个实体的数据。
  • 添加类Aspose.ThreeD.Render.DescriptorSetUpdater -IDescriptorSet不提供更改其有界描述符的接口，需要一个DescriptorSetUpdater才能向GPU提交多个更新。
  • 添加类Aspose.ThreeD.RendererVariableManager -手动渲染实体时，通常需要一些内部变量，例如视图/投影矩阵，这些变量可以在rendervariablemanager中找到。
  • 添加类Aspose.ThreeD.Render.SPIRVSource -创建着色器程序实例时，需要spir-v源，spir-v是从GLSL或其他着色器语言编译的Vulkan的字节代码。
  • 添加类Aspose.ThreeD.实用程序.IOUtils -提供了一些将矩阵/向量写入BinaryWriter的扩展方法。
  • 添加类Aspose.ThreeD.Render.IPipeline -在GPU端绘制的预烘焙操作序列，当图形流水线创建时，底层GPU驱动程序将不需要在绘制调用中重新验证渲染状态/重新编译着色器，这可以大大提高渲染性能。

类删除

  • 删除类Aspose.ThreeD.渲染资源 -旧渲染体系结构中最小渲染任务的基类。新的渲染器将为文件读/写设计的对象模型和渲染实现分开，因此不再需要RenderableResource。
