Question Ranger (and other ships) from Interstellar?

[Koloss]

I am so much looking forward to travel to Saturn with this ship(s)! Can't wait :woohoo:

 

[gattispilot]

Well. I thought we were close now With a fully loaded Endurance 2 rangers and 2 landers I get 5 fps. Endurance fully loaded Vc I get 19 fps. But add the rangers and landers it drops. Not sure why in vc/cockpit mode though

 

[Koloss]

So on my laptop it will be more like 1 or 0.5 fps

 

[gattispilot]

In D3D9 I get 40-50. But in regular graphics it changes if I switch to lander it goes up to 20. not sure what to do to fix this?

 

[gattispilot]

Endurance cockpit notice the fps

exterior with 2 landers

interior lander

These were d3d9. Not sure if any I can do

 

[Urwumpe]

Fix: Paint on a texture/surface only if you need to.
Fix: If you can, don't paint on textures, but manipulate vertices.
Fix: The less your code does, the faster it happens.


Not the wind, not the flag; mind is moving.

So like the green level bars. Make green rectangle mesh and scale it?

For example. Look also at the page flipping definition here and meditate about it:

https://en.wikipedia.org/wiki/Multiple_buffering#Double_buffering_in_computer_graphics

 

[gattispilot]

Interesting?

Well I guess I could make it without a VC and see what the loss or gain of FPS is. But that would take away the feel.

We at one time thought about making a mfd to deal with all the engine and cargo info

 

[gattispilot]

no vc I get 115 fps

 

[marcogavazzeni]

115 fps without VC are few, are using the D3D9? My ship has more than 100 fps with 4 MFD's and at least a dozen indicators, I think you have a very large mesh and a wrong code.

 

[gattispilot]

yes d3d9.
On the size the Endurance
80 groups
71058 vert
54480 triangles

vc mesh
85 groups
1518 vert
760 triangles

I can post the code if that will help

 

[marcogavazzeni]

I'm not a programmer, I just used the codes in the SDK. First of all a lighter vessel.

But your analysis is right. The issue is most likely the painting code. The last version of the code I saw was terribly slow by using the slowest kind of rendering every time step.

 

[gattispilot]

Not sure about the lighter vessel?

On the endurance this is the only paint on the texture. The rest is mfd or mesh group movement

At one point we saw that if in the copilot view the cargo status would not change unless you switched views


For the cargo there are 3 x16 cubes (red, yellow, green) that move back and forth depending on the status of the cargo.

I see the bump up in framerate without the VC but I think the experience is more immersive with the VC.

Here is the code for the vc for the lander:

[marcogavazzeni]

But your analysis is right. The issue is most likely the painting code. The last version of the code I saw was terribly slow by using the slowest kind of rendering every time step.

I believe that the main problem is the will to run an elephant like a gazelle, large mesh and thick texture does not make the vessel fast, if Gattis do not understand this concept is useless post codes, where I see writing as 1024 x 1024, and ships with 50,000 polygons, maybe in 2/3/4 years the Gattis vessel will be fluid, with microprocessors quantum .....

 

[gattispilot]

What?

So are you saying if will be slow because of the size? or the code.

I really can't do much on the size.

 

[marcogavazzeni]

I think....

1-must reduce the number of vertices of your vessel:

On the size the Endurance
80 groups
71058 vert
54480 triangles

"As a rough guideline, I would suggest to keep the vertex count below 10 000 vertices
for each spacecraft"(3DModel pdf)

2-It must reduce the size of the texture and bar indicators

If you have a vessel that no VC, has 115 fps, if you add the VC indicators with bar, you lose even more fps, the more the bars are large, so you reduce the polygons of your vessel, and reduce the size of the bars if you want to have a fluid simulation.

A proverb says to want the barrel full and the wife drunk.
