Terminator

[Vincent]

We should probably make the terminator color settable as well.

Chris,

The terminator color (and opacity), as well as any visible region mark color, is already settable using:

Code: Select all

earth = celestia:find("Sol/Earth")
sol = celestia:find("Sol")

earth:addreferencemark{type = "visible region", color = "red", opacity = 0.5, target = sol}

Chris,

The terminator color (and opacity), as well as any visible region mark color, is already settable using:
[code]earth = celestia:find("Sol/Earth")
sol = celestia:find("Sol")

earth:addreferencemark{type = "visible region", color = "red", opacity = 0.5, target = sol}

Right--I mean that the default visible region color should be settable.

One would have to define each bodies? no general setting like other elements (via setlinecolor)?

Here's an interesting usage of visibility circles. The visible regions of GPS satellites are drawn in cyan, and the the visible regions of ISS and Hubble are green:

Interesting! Another display for an eventual contextual Guides submenu...

Thanks guys, the color commands are nicely working. Here are the colors I'm using in my start.celx script :

Code: Select all

celestia:setlinecolor("planetographicgrid", 0.15, 0.525, 0.525)
celestia:setlinecolor("planetequator", 0.4, 0.9, 1.0)
celestia:setlabelcolor("planetographicgrid", 0.2, 0.9, 1.0)

Haven't tested your set Cham, but this stuff should stay neutral in the official release; the yellow terminator seems fine at it is related to the sun vector and to the common idea sun = yellow...
The equator in green seems fine to me too cause if I'm not wrong it's the color used in many maps no?

Chris,

The color field is optional. If not precised, the default yellow color is used.
Then, you're right, there's currently no way to change this default color via setlinecolor.

I'm trying to decide what to do about that--should the grid be displayed over the cloud layer when clouds are enabled and on the ground otherwise? Selden and I discussed this issue briefly and agreed that that seemed the best option.

I think it would be much better to see the grid above the clouds and the ground, in all cases.

Also, the grid color used should be a parameter in the start script (as all other colors...), since there may be some confusion between the grid lines and spacecraft trajectories (especially in the case of labels and grid coordinates).

Please make the grid on the ground or over the clouds a setting that can be adjusted, so everybody will be happy.
