I have put one button in my demo project for transforming an object using camera.Īnd as above you can use QuaternionRotation3D or AxisAngleRotation3D. We can transform objects using camera's position and up direction also. RotateTransform3D r1 = new RotateTransform3D(a) RotateTransform3D r = new RotateTransform3D(qr) ĪxisAngleRotation3D a = new AxisAngleRotation3D() QuaternionRotation3D qr = new QuaternionRotation3D( new Quaternion(axisArg, stepAngleArg* 180 Math.PI)) Transform3DGroup group = solidCubeMV3D.Transform as Transform3DGroup
GEOMODEL SOLIDS CODE
Now, we have Axis and Angle so we can now rotate the object using any one of Code Block below. Or you can also use the following formula.ĭouble stepAngle = 0.01 * Math.Sqrt( Math.Pow(dx, 2) + Math.Pow(dy, 2)) You can give any constant value to Angle of Rotation (stepAngle). In ordert to calculate rotationAxis we will first calculate mouseMoveAngle after adding 90 degree in it that will give us rotationAxisAngle and then as shown in the image below using some basic mathematics we can find rotationAxis. We can decide Rotation Axis and angle using the mouse movement and some calculations. In order to transform an object you have to decide two thingsĢ. Here, you can compare yourself as a camera. One cube is on table and you are rotating around the cube or table, One cube is in your hand and you are rotating it with your fingers. To transform objects in Viewport3D we have two options.Ī. You can see that points P3 and P4 are used twise. ScreenSpaceLines3D wireFrameCube = new ScreenSpaceLines3D() You will not see Red points and labels of points. NOTE: after using the code below you just see straight line in ViewPort3D. NOTE: Suppose a line is being drawn using four points then two intermediate points will be used two times or we add intermediate points twice.Ĭode to draw this line in viewport is as below. That's it you have created wireframe cube. SECOND:Simply and directly add the ScreenSpaceLines3D(wireFrameCube) to the Viewport3D(mainViewPort). WireFrameCube.Transform = new Transform3DGroup() WireFrameCube = new ScreenSpaceLines3D()

To add reference of 3DTool in your project Following the steps:ģ.Select: Add References… will open new dialogue boxįIRST: Create the instance of ScreenSpaceLines3D(wireFrameCube) and set it's three properties and that is "Thickness", "Color", "Points".Īnd also set the "Transform" property to later use in Rotation of "wireFrameCube". I have added it in my DemoProject " 3DTOOL DLL" folder. In order to draw wireframe object you need 3DTool.dll. Add MODELVISUA元D in VIEWPORT3D (solidCube) NOTE: Assign transform property of (solidCubeMV3D) to later use in rotation of object.įOURTH:Add ModelVisual3D(solidCubeMV3D) in the Viewport3D(mainViewPort) SolidCubeMV3D.Transform = new Transform3DGroup() it will later use to rotate the object Store the instance of Transform3DGroup class in Transform Property of "solidCubeMV3D" Model3DGroup cubeM3DGroup = new Model3DGroup() Ĭ(CreateTriangleFacet(p3, p2, p6)) Ĭ(CreateTriangleFacet(p3, p6, p7)) Ĭ(CreateTriangleFacet(p2, p1, p5)) Ĭ(CreateTriangleFacet(p2, p5, p6)) Ĭ(CreateTriangleFacet(p1, p0, p4)) Ĭ(CreateTriangleFacet(p1, p4, p5)) Ĭ(CreateTriangleFacet(p0, p3, p7)) Ĭ(CreateTriangleFacet(p0, p7, p4)) Ĭ(CreateTriangleFacet(p7, p6, p5)) Ĭ(CreateTriangleFacet(p7, p5, p4)) Ĭ(CreateTriangleFacet(p2, p3, p0)) Ĭ(CreateTriangleFacet(p2, p0, p1)) THIRD: Add collection of Model3DGroup(cubeM3DGroup) in ModelVisual3D(solidCubeMV3D). You can also see the same code in demo projects. To set camera and light see the code below and image I think I don't need to write any thing for explaining definitions. There are four basic materials used in WPF as below.įor more detailed explanation on material go here Material represents the texture of the 3D Geometries. So, each position has 3 normals in our case. I have added 24 normals for 8 positions of the cube because each point of position will be used by 3 triangles. Transform above cube's that is Solid and Wire frame cube.One thing that shocked me was that WPF does not render wireframe objects but thank God that the 3DTool provides the ScreenSpaceLine3D class that allows us to render wireframe objects. And this article is the result of this process. In the very beginning I decided to make a project that (1) renders 3D objects (2) Wireframe object and (3) does basic operations for 3D objects. The result of this was I have done some R&D related to this topics and I found that WPF will help me in Rendering of 3D object and Transformation of 3D objects. I have just completed my Graduation in IT and at the very beginning of my career I am facing the projects or problems related to 3D Graphics, Rendering of 3D objects in computer screen and perform some basic operation over 3D object.
