//----------------------------------------------------------------------------- // // Sample Name: BarGraph Sample // // Copyright (c) 1999-2000 Microsoft Corporation. All rights reserved. // //----------------------------------------------------------------------------- Description =========== The BarGraph sample describes how one might use Direct3D for graphic visualization. It makes heavy use of the RenderToSurface features of D3DX to render text and bitmaps dynamically. Path ==== Source: Mssdk\Samples\Multimedia\VBSamples\Direct3D\BarGraph Executable: Mssdk\Samples\Multimedia\VBSamples\Direct3D\Bin User's Guide ============ right click to bring up a pop up menu. from this menu you can load new data from a .csv (comma delimeted file) such a file can be exported from excel or any spreadsheet package. The file must be formated such that the first row and columns are headers that title the data. They can contain the tag TEXTURE:filename.bmp to indicate that the header contains a picture. the rest of the data must be numeric see bargraphdata.csv in Mssd\Samples\Multimedia\VBSamples\Media for an example Holding the left mouse button and dragging will rotate the graph. Right Arrow moves the camera right Left Arrow moves the camera left Up Arrow moves the camera up Down Arrow moves the camera down W moves the camera forward S moves the camera backward E rotates the camera right Q rotates the camera left A rotates the camera up Z rotates the camera down Programming Notes ================= This sample makes use of common DirectX code (consisting of helper functions, etc.) that is shared with other samples on the DirectX SDK.
