New Classes

Added new class Aspose.ThreeD.Render.PushConstant

 /// <summary>

    /// A utility to provide data to shader through push constant.

    /// </summary>

    public class PushConstant

    {

        /// <summary>

        /// Constructor of the <see cref="PushConstant"/>

        /// </summary>

        public PushConstant();

        /// <summary>

        /// Write the matrix to the constant

        /// </summary>

        /// <param name="mat">The matrix to write</param>

        public PushConstant Write(FMatrix4 mat);

        /// <summary>

        /// Write a int value to the constant

        /// </summary>

        /// <param name="n"></param>

        public PushConstant Write(int n);


        /// <summary>

        /// Write a float value to the constant

        /// </summary>

        /// <param name="f"></param>

        public PushConstant Write(float f);

        /// <summary>

        /// Write a 4-component vector to the constant

        /// </summary>

        /// <param name="vec"></param>

        public PushConstant Write(FVector4 vec);

        /// <summary>

        /// Write a 3-component vector to the constant

        /// </summary>

        /// <param name="vec"></param>

        public PushConstant Write(FVector3 vec);

        /// <summary>

        /// Write a 4-component vector to the constant

        /// </summary>

        /// <param name="x"></param>

        /// <param name="y"></param>

        /// <param name="z"></param>

        /// <param name="w"></param>

        public PushConstant Write(float x, float y, float z, float w);


        /// <summary>

        /// Commit prepared data to graphics pipeline.

        /// </summary>

        /// <param name="stage"></param>

        /// <param name="commandList"></param>

        public PushConstant Commit(ShaderStage stage, ICommandList commandList);

    }

Usage

This simplifies the preparation of push constant in rendering as shown below.

 //The old code in Background.cs in AssetBrowser to prepare data for background shader:

  /*

            float[] data =

            {

                1000, 0, 0, 0,//height

                0.22f, 0.2f, 0.13f, 1.0f,//upper color

                0.2f, 0.3f, 0.3f, 1.0f//lower color

            };

            var constants = new byte[data.Length * 4];

            Buffer.BlockCopy(data, 0, constants, 0, constants.Length);

            commandList.PushConstants(ShaderStage.FragmentShader, constants)

  */

//The new code by using PushConstant, you don't need to calculate the data's alignment manually:





//Push the height/upper color/lower color to the fragment shader

pushConstant

     .Write(1000.0f)

     .Write(0.22f, 0.2f, 0.13f, 1.0f)

     .Write(0.2f, 0.3f, 0.3f, 1.0f)

     .Commit(ShaderStage.FragmentShader, commandList);
