=== Description ===
<div class="tableNormal">

This plugin allows you to import a Mars Surface from the [http://www.uahirise.org HiRISE] project directly into Blender.

==== Details ====
This script imports a standard HiRISE DTM (*.IMG), reads the embedded PDS label and decodes the raster elevations to create a mesh in the current view. The lowest value of the DTM is set to Z=0 in blender coordinates and the upper left corner of the image is placed at X=0,Y=0 in the Blender world.

==== Different Resolutions ====
Since HiRISE DTMs are quite large for most machines that Blender runs on today, the script has the ability to sample/average portions of the image into single pixels which effectively reduces the resolution but also reduces the amount of time/memory that Blender needs to work with the DTM. Re-importing a higher resolution later on will place the DTM in exactly the same place that the original DTM was imported to (size/scale matching as well) so that creating animations/previews can be done with much less effort.

This is really useful for prototyping your scene. Import a low-res version, get all of your animation/modeling done and rendered and then import a higher resolution mesh for the final render.

==== A few words on scale ====
When importing for the first time, leave the scale=0.01 so that the mesh is not huge. Setting scale=1 will map the DTM coordinates 1:1 with Blender units. The result is a very large mesh that can't be viewed easily in the default view.

=== Usage ===
<div class="tableNormal">
1) choose a published HiRISE DTM from [http://www.uahirise.org/dtm/ http://www.uahirise.org/dtm]

[[File:ImportHiRISE_DTM_ChooseWebDTM.jpeg|600px]]

2) download the linked "DTM" image
Warning: these files can be quite large

[[File:ImportHiRISE_DTM_WebView.jpeg|600px]]

3) Inside of Blender navigate:
File -> Import -> HiRISE DTM from PDS IMG (*.IMG)

4) Select the DTM and desired settings

[[File:ImportHiRISE_DTM_Settings.jpeg|600px]]

a) Select your bin/scale settings.

{|
|+Binning Methods
|-
|None || This will import the DTM without downsampling. Warning: this can take a lot of memory
|-
|2x2 || Create one value for each 2x2 region of the DTM by averaging them
|-
|6x6 || Create one value for each 6x6 region of the DTM by averaging them
|-
|6x6 Fast || Create one value for each 6x6 region of the DTM by sampling a single value
|-
|12x12 || Create one value for each 12x12 region of the DTM by averaging them
|-
|12x12 Fast || Create one value for each 12x12 region of the DTM by sampling a single value
|}

b) Select the DTM you downloaded

c) Select the "Import HiRISE DTM" button to start the import

5) Now just wait.
NB: These DTMs are big and take a whole lot of floating point manipulation to import.

6) Enjoy/manipulate/render the surface of mars as you would any other mesh in Blender.

=== Installation ===
<div class="tableNormal">

1) Download the files into a folder named "io_mesh_img".

2) Open User Preferences (File -> User Preferences)

3) Select the "Add-Ons" tab

4) Click the "Install Add-On" button at the bottom of the window

5) Navigate to the io_mesh_img folder and click the "Install Add-On" button

6) Type in "HiRISE" into the search field and enable the plugin:
Import/Export: HiRISE DTM from PDS IMG
