Viscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma). Lower temperature magmas have higher viscosity than higher temperature magmas (viscosity decreases with increasing temperature of the magma).
Google does not specifically recommend either DirectX or OpenGL for Google Earth. You can configure Google Earth to operate in either DirectX or OpenGL rendering modes.If your system crashes or performs poorly in one mode, Google recommends you switch to the other mode.penGL Overview. OpenGL is a platform-neutral, open API for rendering graphic images. Although the API is different, OpenGL provides Google Earth with the same graphics performance enhancements as DirectX. OpenGL was originally developed by Silicon Graphics Incorporated.
Capturing Google Earth images to use as base maps in SketchUp. You can capture an image from Google Earth and use it as a base map in SketchUp. This allows you to develop a model that is spatially referenced and it also offers any easy way to bring a terrain map into your model.In Google Earth navigate to your site along the Anacostia River.lick on Get Model (or Download Model) and watch the model of the bridge appear in your SketchUp model of the Anacostia. Now, click on Place Model. and watch Google Earth fly you to the newly inserted Frederick Douglass Memorial Bridge.
