Overview

Accompanying the releases of SpeedTreeRT 1.7, SpeedTreeCAD 3.4 & SpeedTreeMAX 3.0 is the totally renovated Tree Model Library v2.0. The Library includes all of the trees available prior to the new release except with numerous improvements artistically and in functionality. Library Pack #3 features 33 species out of the Full Tree Library. Highlights include:

•	169 individual '.spt' tree models, divided into 33 Species of trees, plants, marine life, cacti, palms & fantasy creations, each with both real time (around 1,000 polygons) and medium detail (1,500 - 15,000 polygons) versions for all of the seasonal variations included.
•	Each model has been totally redesigned, buffed up, and re-textured to be compliant with our current (and always rising) standards and tree creation techniques. All tree species have been renovated in the following ways:
	•	All textures for all of the trees have been improved to the quality of those seen in the Trees of Pangaea™ demo by normalizing the values to create a more convincing "sunlit" effect.
	•	New SpeedTreeRT 1.7 wind algorithms have been implemented and tuned for all of the trees (requires SpeedTreeCAD 3.4).
	•	Improved LOD transitions
	•	Lowered polygon counts for both real time (RT) and medium detail (MD) models.
•	Easy to use and improved navigation system, now with 800x600 detail shots for every species.
•	Many of the tree models seen in our demos, including Trees of Pangaea™
•	New to the tree library is the Frond Model, Leaf Model, and Bark Texture Libraries; a collection of .spt and .tga files designed as templates for exporting image maps to be used on custom trees. These .spt files only require the user to apply the correct texture from his or her tree project, or our texture library, and follow the simple directions outlined in our artists' tutorials (SpeedTreeCAD) for creating frond branch textures and leaf maps.

Use the tree control located on the left hand side of this page to preview all of the trees available from IDV, Inc. for use with the SpeedTree product offerings. Trees are organized into libraries and sorted by categories including conifers, broadleaves, palms and cycads, shrubs, and miscellaneous tree models. SpeedTreeRT customers receive all tree models made prior to and during their active support period.

The first part of all tree models indicates what type of tree the model represents. Identifiers used are typically common names. Use the tree control to the left to locate trees based on their scientific names, common names, or search alphabetically.

The detail section of the filename indicates roughly how many total triangles (leaves, branches, and fronds) are generated when a tree is computed with the parameters in the file. Remember, exact triangle counts vary with the seed being used. The list below displays the different detail levels and the triangle counts they represent. Triangle counts listed below are at the highest level-of-detail. SpeedTreeRT users should note that lower levels of detail (all the way down to a billboard) are generated automatically by SpeedTree.

Abbreviation	Meaning	Triangle range	Common Uses
HD	High Detail	15,000+	Off-line animation
MD	Medium Detail	3,000 - 15,000	Off-line animation, real-time scenes with few trees
RT	Real-time	300 - 3000	Video games, military simulations, real-time environments
LD	Low Detail	<300	Off-line animation for trees at great distances

The final part of the filename is reserved for any extra information the modeler wishes to be known about the model. Common examples include "Fall" to indicate the season, "Blooms" to indicate the presence of flowers on the model (e.g., Crepe Myrtle, Southern Magnolia), and "Low" to indicate particularly low polygon counts.
