Visualize cylinders and POCAM with steamshovel

[fiedl]

I would like to display GCD files with hole-ice or cable cylinders and POCAM devices with the steamshovel event viewer.

Resources:

• Steamshovel patches of my original hole-ice study: https://github.com/fiedl/hole-ice-study/tree/master/patches/steamshovel
• POCAM scripts by Felix Schmuckermaier (@fschmuckermaier): https://github.com/fschmuckermaier/POCAM_scripts
• Migration of hole-ice clsim into the new combo repo: https://github.com/fiedl/icecube-git-migration/issues/14
• New combo repo: https://github.com/IceCube-SPNO/IceTrayCombo

I'm adding the HoleIce.py artist and use my old gcd test file:

The cylinder is visible, but the DOMs look quite huge. I'm applying this patch to reduce them to their real size. This will need some work to make this not the default later.

This looks better, but there seems to be a clipping issue. This reminds me of an issue where Alexander Kappes had a solution.

Alexander Kappes, 2014-07-11 In I3Camera, change the near parameter to prevent hiding nearby objects ("clipping").

// Camera.h

// old setting:
    I3Camera() :
        fovy(45.), w(100.), h(100.), near(10.0), far(1000000.0)

// new setting:
    I3Camera() :
        fovy(45.), w(100.), h(100.), near(0.1), far(1000000.0)

I'm adding a simple steamshovel artist for the POCAM device.
