The 'Renderer' (a.k.a RenderView, RenderViewForm) is the main 3D visualization tool within Tarsier. Its function is to display geospatial information from

For any given scene the Renderer must decide what should be drawn, in what order to draw things, and how things should be drawn. For example, lets say we are viewing an ocean scene from above the waters surface looking down. Our view angle includes bathymetric data stored as a raster, habitat characterization data (also in raster format), data on kelp distribution and abundance (raster again), fish locations (table data), and boundaries of Marine Protected Areas stored as vectors. Perhaps some of these things change with time (e.g. the fish locations). ..unfinished..

Renderer Tabs

The Render View Form is the GUI for the Renderer. The many options and controls for the renderer are accessed via tabs at the top of the form. These tabs allow you to input and access the data, perform operations on the data (i.e. make terrain), and change how the data is visualized.

General Tab

Increase the sharpness of your rendered image by increasing the number of accumulations. Increasing the number of accululations will increase to time for Tarsier to render an image. Use wisely.

Sun Tab

You can set the sun feature in your render to automatically adjust to your model time object. Meaning when your time is at a period of night, your render will be darker then when your time is at a period of day.

Manually adjust the position of the sun

  • Elevation: colors will apear brighter when the sun is higher in the sky
  • Azimuth: features in your DEM with different strikes will be highlighted as the sun is shining from different directions

Manually adjust the RGBs (primary colors... red, blue and green) of your data

  • Sky: sets the color of the sky
  • Ambient: visibility of the data not dependent on the sun settings
  • Diffusion: this essentially adjusts the blending of colors

Rec Tab

Record flights or take a still frame picture of your render Tarsier tutorial: Simple fly-through

Time Tab

Can open a model time object ( .tti ) for your vizualization.

Frus Tab

Change the amount of data that is being rendered in each frame.

  • "Near" is the distance that data will be rendered from the camera
  • "Far" is the distance that data will be rendered away from the camera

Rendering less data will take less time, but rendering more data may be necessary situationally. Chose wisely.

Econ Tab

Allows the user to adjust the quality of the render image at the expense of time

  • Detail value: determines the amount of detail drawn between cell values
  • Re-origin now: rebuilds the render any time the user wants
  • Rebuild distance: rebuilds the render automatically when the camera moves a specified distance
  • Rebuild angle: rebuilds the render automatically when the camera rotates a specified angle

Rebuilds take time, less rebuilds mean faster flying. Chose wisely.

Tex Tab

Vec Tab

Allows you to incorporate vector data ( .tvc ) into your 3D render.

World Tab

World2 Tab

Ocean Tab

Sky Tab

Fog Tab

HPlane Tab

3DObj Tab

Graphs Tab

Ven Tab

This tab allows you to overlay another raster over the top of the terrain - use a raster as a veneer. The height above the terrain is defined by the value of the veneer raster inversely scaled by a "density" value (value in the "Den" box). This feature was initially added to visualize snowpack dynamics. However, it can be used for a variety of purposes, such as adding rugosity to rocky terrain.

Ven2 Tab

Raster Tab

Where you create your 3D representation of your raster data ( TRA ).

  • Enable raster in the top left box
  • Change the color scheme of your data by clicking the "C" button
  • Follow this tutorial Tarsier tutorial: Renderer

R2, R3 Tab

Allows for the rendering of multiple sets of raster data ( TRA ).
