The Drape Image layer is offered in most RockWorks programs that generate 3D scenes. It is used to display a raster image (BMP, JPG, EMF and WMF, PCX, PNG, TGA, TIFF) floating in 3D space, warped over an existing RockWorks grid (surface) model. Click on the Drape Image tab to access these settings.
! This program will stretch the image to fill the grid model boundaries.
! The image and the grid model must reside in the current project folder.
- Drape Image
Check this item to include a draped image in your 3D scene.
Click on this tab to access the drape settings.
- Image Source
- Project Image: Click this option to drape the current Project Image.
- Other Image: Click this option to select a different raster image to drape.
- File Name: Browse for the name of the raster image you want to drape over the grid model. The supported file types are listed above.
- Drape Options
- Grid Name: Browse for the name of the surface model (.RwGrd file) that contains the elevations over which the image is to be draped. This can be a ground surface grid model, a formation grid model, etc.
- Layer Name: Type in a name for this layer; it will simply be used to label the image in RockPlot3D. For example, if the image represents a satellite image, you might name this layer "Satellite Image."
- Vertical Offset: Use this setting to offset the image above or below the grid model's surface. This can prevent interference between them if plotted together in RockPlot3D. The offset is entered in your project units; if your coordinates represent feet and you enter "5" then the draped image will be created at 5 feet above the grid model's surface. If set to 0, the image elevations will match the grid.
- Set Transparent Color: Insert a check in this box if you want to specify a specific color in the bitmap image to be displayed transparent. For example if the image has a white background and you would like that part to be see-through, you would select white.
If activated, click on the color box to choose the image color that is to be set to transparent.
