The Shading section enables you to set the manner in which colours are applied to individual grid
cells during the rendering process. There are two options: Smooth and Flat.
• Smooth renders a colour gradient between each grid cell when rendering a scene. This can
greatly improve the appearance of low-resolution grids (see the figure below on the left).
• Flat assigns one colour to each grid cell during the rendering process (see the figure below on
the right).
The Bitmap Size section enables you to set the resolution of the rendered image. The Height and
Width settings, measured in pixels, can increase or decrease the resolution or quality of the
rendered image. High-resolution images can be panned but not zoomed in GridView. You can use
MapInfo Professional or any raster/paint program to zoom images saved with the Export to .bmp &
.tab command found on the File menu.
The Scene section enables you to set the characteristics that affect the visual appearance of the
rendered scene. Increasing the shininess value of the surface will increase its overall gleam, while
decreasing the shininess value will produce a duller, waxier looking surface. Specular Reflectance
can be increased to produce more highlights on the surface.
The Null Value Colour button enables you to set the colour applied to areas of a grid where there
are null values. A null value is an arbitrary numeric value given to those grid cells that did not obtain
a calculated value at the time of interpolation or that have been trimmed away at a later time. This
Solid displays a continuous colour
surface. Wireframe displays a wireframe
mesh.
Smooth renders a continuous colour
gradient. Flat assigns one colour to each cell.
