blender

blender is a free and open source 3D animation suite. it supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering and motion tracking, even video editing and game creation. 

points covered in session:

navigation around user interface 

optimization of user interface

rendering, camera positions and render presets

below are two renders taken from a simple shape made in blender, experimenting with camera positions and lighting

importing 3d models and photographs

creating particle systems, exploding and other modifiers

below are a series of renders taken from a 3d model produced in rhino of a old dry dock. this model was imported into blender, replicated, and had different modifiders applied to it to produce these cool renders

final GIS workshop

points covered in session:

layout slides with title and key

using the layout mode of ArcMap it is possible to add text, images, legends, north arrows and scale bars

layering map over the terrain of our 3d model made in arcscene. the software recognizes the different heights of the raster image using the different pixel colors as refrence points. the base height can be changed to the DTM raster image and the contours can be exaggerated in the scene properties of the file.

 

production of animations of terrain model

GIS 2nd round

points covered in session:

adding in and editing contours lines, this can be done to different values, for example the in the two images below the brighter green lines are 1m contours, the darker are 5m contours

the contours can also be labeled 

the height data can be represented as a heat map as well, then the contours can be overlayed

overlaying different maps

hydrology analysis was also used, for this the vector image must be converted into a raster using feature to raster. flow accumulation creates a raster of accumulated flow to each cell and the image below was produced

3d mapping using ArcGIS

points covered in session:

introduction to GIS 

review of how to get data from Digimap, downloading the required maps and opening them in arc catalog, creating a geo-database and keeping maps organised

using the dtm make a 3D model from topography
