Issue #1112: [experimental] document how to use the `get_` and `set_` functions in the VR objects (yt_analysis/yt)

New issue 1112: [experimental] document how to use the `get_` and `set_` functions in the VR objects https://bitbucket.org/yt_analysis/yt/issues/1112/experimental-document-how-… Cameron Hummels: Add narrative docs demonstrating how to get the source, camera, get transfer function, etc. so one can change them. `get_` and `set_` functions in the source are opaque.

New issue 1111: [experimental] cross-reference of VR docs with VR recipes https://bitbucket.org/yt_analysis/yt/issues/1111/experimental-cross-referen… Cameron Hummels: We should link to subsections of the VR docs in the relevant cookbook recipes not just to VR as a whole.

New issue 1110: [experimental] VR Camera Movement recipe improvements https://bitbucket.org/yt_analysis/yt/issues/1110/experimental-vr-camera-mov… Cameron Hummels: Camera movement cookbook needs to be improved to make images that make sense; right now it's very difficult to tell what's going on with the panning and zooming and rotating.

Issue #1109: [experimental] default way to write images in VR? (yt_analysis/yt)
by Cameron Hummels 14 Oct '15

New issue 1109: [experimental] default way to write images in VR? https://bitbucket.org/yt_analysis/yt/issues/1109/experimental-default-way-t… Cameron Hummels: Note differences in ways to write images in VR: (1) you specify an fname in the yt.volume_render() function originally (2) you get the resulting im object from yt.volume_render() and then write it using im.write_png(fname), (3) you take the resulting sc object from yt.volume_render() and then sc.render(fname). i guess it is good to have these three methods for getting the images to file, but it might be worthwhile to explicitly state that there are three methods for writing your VR to file, so people don't get confused on which is the main method (as i did and just had to figure it out by looking through different examples, source, etc).

Issue #1108: [experimental] examples for using different VR lenses (yt_analysis/yt)

New issue 1108: [experimental] examples for using different VR lenses https://bitbucket.org/yt_analysis/yt/issues/1108/experimental-examples-for-… Cameron Hummels: Add examples for using all the different available lenses to the cookbook or narrative docs. I think @jisuoqing did something on this recently, but I don't recall if it made it into the repo.

Issue #1107: [experimental] consistency in camera motion (yt_analysis/yt)
by Cameron Hummels 14 Oct '15

New issue 1107: [experimental] consistency in camera motion https://bitbucket.org/yt_analysis/yt/issues/1107/experimental-consistency-i… Cameron Hummels: The various means of moving the camera can be confusing. As an example, `rotate()` doesn't rotate the direction of the camera so much as it rotates the position of the camera relative to its focus. `yaw`, and `pitch` do the same thing, even though those are normally words associated with changing the orientation of something and not it's position. How to reconcile? I'm not opposed to leaving as is, but we need to be explicit about this in narrative docs and docstrings so as to not confuse users.

Issue #1106: [experimental] demonstrate how to use the VR annotations in the docs (yt_analysis/yt)

New issue 1106: [experimental] demonstrate how to use the VR annotations in the docs https://bitbucket.org/yt_analysis/yt/issues/1106/experimental-demonstrate-h… Cameron Hummels: VR annotations (e.g. annotate_grids()) don't get much play in the cookbook or in the narrative docs to show how to use them.

Issue #1105: [experimental] make subpage in docs for TransferFunctionHelper (yt_analysis/yt)
by Cameron Hummels 14 Oct '15

New issue 1105: [experimental] make subpage in docs for TransferFunctionHelper https://bitbucket.org/yt_analysis/yt/issues/1105/experimental-make-subpage-… Cameron Hummels: in the VR docs, TransferFunctionHelper has a very useful long notebook demonstrating how to use it. unfortunately, it's right in the middle of the narrative docs, and it really breaks up progression of the description of using VR. I think it should be split out into a different page in the narrative docs and linked there as well from the cookbook/notebooks page.

Issue #1104: [experimental] transfer functions move from log to linear space for VR (yt_analysis/yt)
by Cameron Hummels 14 Oct '15

14 Oct '15

New issue 1104: [experimental] transfer functions move from log to linear space for VR https://bitbucket.org/yt_analysis/yt/issues/1104/experimental-transfer-func… Cameron Hummels: Transfer functions operate in log space for fields that are logged. This should be done in the linear space of the fields. Can be very confusing.

Issue #1103: [experimental] render() with off_axis_projection yields no image (yt_analysis/yt)
by Cameron Hummels 14 Oct '15

New issue 1103: [experimental] render() with off_axis_projection yields no image https://bitbucket.org/yt_analysis/yt/issues/1103/experimental-render-with Cameron Hummels: the way to render an off_axis_projection requires yt.write_image() instead of sc.render() like the VRs even though it is using the same infrastructure. inconsistent. why? sc.render() *runs*, but even with a clip_ratio, it just gives a black screen because all of the values are NaNs. bug? problem? if i'm doing it wrong, perhaps others will, and it could be documented how to use it correctly.
