android hunting simulator

Finally released my rifle hunting simulator for android.
The app let you practice rifle shooting in various wind and distance conditions, and then see impact data for the bullet.
Available for free at google play

realtime animals

Some real time animals created in blender3d, about 800 triangles each.

random walk path

After alot of trying to have realistic movement in my simulator I finally figured out how to make a good random walk path generation, the speed and direction is generated on the fly as the program runs.
Basically it pics a random targetspeed between 0 -3 m/s to achieve at a random intervall between 1-4 seconds. For the direction it increments at a random target angle at random interwall between 1-5 seconds
This is the result after 10 minutes of walking, each grid is 10meter.
Programmed in the super awesome open sourced Irrlicht 3d engine.

Hunting simulator screens

Two screens showing low light simulation and projectile hit debugs with a specified caliber.
This training software is planned to be made available for public download soon.

223 remington zeroed at 100 meter.
Roedeer 200 meter, heading 140degree.
Wind 3m/s from left

Result, notice the impact of wind at this range

Dense 3d point cloud reconstruction old buildings

Another test of 3d reconstruction, this is from Otternes farm in Flåm, Norway.
tried to capture some details just to test how it worked out.

First set reconstructed quite well

This one I should have taken some more images, but it still worked out accurate cordinates

Dense 3d point cloud reconstruction of mountainside

Testing large scale point cloud reconstruction of a mountainside.
This area was about 150-200m wide, reconstruction makes it possible to do a detailed inspection of the mountainside topography.
Used a set of 13 images on this one and imageresolution of 2144 pix wide. 430 000 vertices.

Dense 3d point cloud reconstruction

Done some testing on dense point cloud 3d reconstruction using the free Bundler .

This is the most robust reconstruction software I have tried so far, and its free:)
Example below successfully reconstructed all visible sides of the object, missing some areas on object that has no detail to track. the fabric the matchbox is lying on is completely reconstructed with no artifacts at all. total verts is about 90 000.
Some notes:
-Camera used  Nikon D300, shot at lowest resolution and Fstop 11.

-Had to add camera to the DB using --checkCameraDatabase and then specifying censor width.

-More images is better, tried with half number of images and result lacked some details.

-calculation time about 15min (i7 920).

-number of vertices gennerated, about 90 000.

Testing normal map texture setup on the gun scope model.
Top image showing the super fast Irrlicht realtime engine and below image is blender 3d glsl mode
Irrlicht diffuse and normal map is 1024x1024 and VBO geometry.
Obviously the buildt in irrlicht engine shaders is optimized for speed compared to blender glsl, but then again it lack some of the quality in blender viewport.
Hopefully some tweeking of  the light/specular setup in Irrlicht will make it better.
