DynamicDataDisplayReloaded

This project is a fork of the DynamicDataDisplayReloaded project based on Microsoft's DynamicDataDisplay project for displaying graphics in a WPF display. If you are looking for the descendent of Microsoft's DynamicDataDisplay project, it is now called InteractiveDataDisplay and is found here https://github.com/microsoft/InteractiveDataDisplay.WPF. The base for this project is a clone of the DynamicDataDisplay Sources v0.3.4703.0 from https://archive.codeplex.com/?p=dynamicdatadisplay

The reason why I am doing this is because I have a whole lot of old code that I want to resurrect that depends on the old DynamicDataDisplay. However not only do I want to use the old DynamicDataDisplay code, but I also want to improve on it. For example I have started adding DirectX9 rendering.

Note: To build the DirectX9 code you will need to install the July 2010 DirectX SDK from Microsoft here https://www.microsoft.com/en-us/download/details.aspx?id=6812 (note this link stopped working in January 2021, then got reinstated)

Here's an example of one of the improvements I've made in the video below. Click the image to go to youtube.

DirectX9 Additions Summary

In the DynamicDataDisplayReloaded project, the data display was expanded to utilise DirectX 9 via SharpDX to show lines and markers for a large performance improvement. For this project, the DirectX component has been further extended to enable the use of textured geometry. Two additional demonstrations are in the current version, showing the potential for textured rectangle object performance.

DirectX9 Demonstrations (some still need work)

A DynamicDataDisplay.SamplesDX9 project has been created to just show DirectX9 samples. There's a memory leak issue that causes things to bog down after clicking on a few of the demos. Restart the app to stop this. The first demo can be found in the side menu under DxRectangleTextured. This demo shows 10,000 markers textured with the distinctive DVD logo. Pressing the Start Animation button animates the display by moving every icon on screen diagonally, bouncing off the defined borders. Pressing the Stop Animation button ceases this animation. Pressing the Reset Positions button moves all icons in the display to a new random position.

The second demo is also found on the side menu with the label DxInstancedRectangleTextured. A major difference is the use of DirectX instancing. Instancing allows the drawing of a large amounts of similar geometry with a smaller amount of draw calls, for a smaller CPU performance impact. To demonstrate the power of instancing, the demo shows 100,000 of the same markers. This demo has the same controls as the textured rectangle textures.

New Features

SharpDX9.DataTypes.DXVertex is a new object that stores a position and texture coordinate for a vertex. This is useful for defining vertices for textured shapes.

SharpDX9.DataTypes.DXRectangle is a helpful structure for defining the points of a rectangle with a given position and width. It has properties to easily retrieve the coordinates of each rectangle edge.

SharpDX9.Helpers.SharpDXHelper contains the functions necessary to create the vertex representation of a rectangle and calculate its texture coordinates. The MakeRectangle function will return a list of vertices from an initial position, width and height.

SharpDX9.Helpers.TextureHelper has helper functions for creating DirectX textures. TextureFromStream can return a texture from a file stream. TextureFromFile can return a texture from file.

SharpDX9.Markers.DxMarkerRectangle takes a collection of vertices and renders a textured rectangle.

SharpDX9.Markers.DxMarkerRectangleInstanced takes a collection of points and vertices and renders textured rectangles using instancing.

SharpDX9.Shaders.DxRectangleTexturedShader contains the vertex shader and pixel shader for a textured shape.

SharpDX9.Shaders.DxRectangleInstancedTexturedShader contains a vertex shader and pixel shader for textured shapes using instancing.

SharpDX9.Triangles.DxTriangleStripTextured gets the transform effects for a textured triangle strip.

SharpDX9.BaseDxTexturePrimitive holds the set of functions for defining the transform effect, vertex buffer and geometry source for the device.

SharpDX9.BaseDxInstancedTexturePrimitive gets transform effect, vertex buffer and geometry source for instanced geometry.
