Select surface with right mousebutton - select "Texture".</h2> <h2>Textures</h2> For textures can JPG and BMP files can be used. Textures can be used for 2D-tags Textures can be applied to Surfaces <b>2D textures for tags:</b> A picture is display always normal to the viewer. Interactive activation: <a href="CAD_TxtG_de.htm#F11">CAD / N-Image</a> <b>Textures for Surfaces:</b> Interactive activation: Modify / Surface Texture. Textures can be applied to the following types of Surfaces: - Planar surfaces - Meshes. The texture can be scaled, moved and rotated activation(<a href="#F1">modifiy</a>). Scale and offset for x and y separately defined. Imagecorrection eg with Gimp: - remove distortion: Tools/transformation/perspectiv - crop image: Tools/transformation/crop - scale image: Image/Image scale For normal quality scale one meter to 100 pixels <hr> <b>Load texture from File</b> Load and activate a texture from a file: Select a JPG or BMP file; the texture name is now displayed as active texture. <b>activate Texture from Surf</b> Activate a already used texture : Select a textured surface. (unhilite texture (in mode VWR only): right mousebutton) Texture and Surface will be activated. You can now <a href="#F1">modifiy</a> the texture - or apply it another surface. <b>apply active Texture</b> Applies the active texture on a surface. Select a surface. <b>Remove Texture</b> Removes the texture of a surface. Select a textured surface. <b>fit Size</b> On: scales the image to the size of the surface Off: the image is applied with its original size <b>Reload</b> Reloads the image of the active texture. (if eg. an image already loaded has been modified ..) <hr> <p><a name="F1"></a></p> <b>Scale - Offest - RotAng / Modify Texture:</b> - Scale X / Y (Scale texture; cursor keys) - Offset X / Y (moving texture; cursor keys) - RotAng (torsion in degrees; Cursor-left/right) Modify the values with the keyboard: update with the return button. Modify the values with the cursor keys: updated dynamically. Next entry with the Tab key. <hr> Analyze dimensions from a photo: Using a photo size should be analyzed: Equalize the photo. Create a surface from a rectangle (in Z=0) with the size of the photo; If the photo displays a area of 3 x 5 meters: S20=REC P(0 0 0) D(5 0 0) D(0 3 0) A20=S20 Apply the texture. Set points (Select / PT -- Position) Measure between points (Analyze Dist). <b>Open / ToDo:</b> Export of textures with VRML .. Support of 16-bit-display Transparent textures .. Billboards .. <hr> Send bugreports and suggestions for improvement to franz.reiter@cadcam.co.at </ PRE> </ HTML>
