Graphics3D.NET is a DotNet WinForms control that can be easily used to incorporate large 3D models and 3D data into your .NET WinForms application. With accelerated OpenGL-based graphics, rendering speed with DotNet is dramatically increased. Entities provided with Graphics3D.NET can be easily translated, rotated and zoomed. Lighting conditions, colors and transparencies can be easily changed to create high quality images fit for 3D visualization, analysis ,and publication; Graphics3D.NET includes lots of base rendering entity set: Points, Lines, Polygons,TriMesh, PolyfaceMesh, Spheres, Disks, Markers, Vectors, Symmetric Tensors, Labels, and 3D surface (generated with implicit or parametric function) etc. They are ready for your large model and data rendering; Graphics3D.NET also provides interfaces of Color table, Contour, and Texture for 3D model and data coloring, contouring, and texturing; Besides various interactive 2D entities such as Legend, Image2D, Progress bar, Chart2D for label layout and data profile, some interactive 3D entities such as clipbox and drawingboard are also provided for viewing complex 3D model and realizing some simple CAD functionalies such as drawing point, line, triangle, and polyline etc; Graphics3D.NET has various viewing mode including Parallel view, Perspective view,Parallel model, Perspective model, and First Person. Accelerators of various mouse actions such as zoom in\out, pick, rotate, pan, query and draw are available for facilitating your coding work; Graphics3D.NET is aiming to support various data format of 3D model. Currently import of DXF, OBJ, 3DS is available;
