Title : Macross Helmet - ( Process )

why the rendering time is too long?
can u tell me what's your rendering options?

The reasons:
1. The modelling was made by nurbs with a super high degree and accuracy.
2. I tried using FinalRender for better shadowing but the timing is even worse, I let it run for tewnty-some hours and it was being rendered half only! So I tried using many spot light focusing at a point to simulate the soft shadow, I know the shadow can be painted and put to one spot light only, which is pointing down, but I just let it goes. I hid the camera & lights in the screen. There are 26 spot light and 1 omni light.
3. 2K x 1.5K resolution for easier photo touch-up using separated z-buffer, shadow and specular layer!

extremely high polygon number for this model

is it your freelance job?

one more question,

why i always see people use rhino+solidwork together gei?
p.s. i know ive product design also teach these combination of package.

Well....polygon....it's not polygon actually,it is NURBS, an kind of representation for surface, it's not accurate & suitable for engineering purpose such as CNC, but already good enough for rendering due to its small size. Within Max, the model was constructed with NURBS(Surface Modelling), which is different from patch, polygon, mesh and boolean modelling.What you see on the screen is NURBS, but it will be converted or simulated to polygons during rendering, and the accuracy you set for the NURBS within MAX is the rate how detail you want the transfer be. The higher the accuracy, the more the polygon and the longer the rendering time!
It's just for fun, not my freelance work. For the code of practice, I would not expose any freelance work to the outside, except with the permission from the client, I'm sorry about that!
Reason for SolidWorks+Rhino:
1.$ saving(SolidWorks-about$50K, Rhino-about$7K)
2. SolidWork is convenient & good at solid modelling(Boolean expression), but rather weak in surface modelling and rendering, although SolidWorks has their own surface modeller and renderer but the performance and convenience are....... so I utilize the strong surface modelling feature of Rhino and combine it with SolidWorks, they are perfect match but still only suitable for modelling, it would be better if you can fully manipulate the BMRT or Flamingo within Rhino for rendering, I've asked the technican in Rhino about the comparison between BMRT, Flamingo, Renderman, FinalRender and Mental Ray, they don't have much comment for this issue, this indicated....

I learnt these softwares after leaving IVE, I learnt Euclid 3, AutoCad and CadKey in IVE(named TC at that time), right now they have Alias/Wavefront product!

我已經無再用max lu,
nurbs modelling唔系即系spline modelling o羊(lightwave)
spline完之後, 再patch, patch 可以control subdivisions
可能我有少少concept上的ｍisunderstand

都系一心學好lightwave先

wa... solidwork 要成50k ga

Patch is different from NURBS, can you accurately model a fillet of R0.50mm? Can you export the patch model for rapid prototyping and CNC machining? Of course not. The control and philosophy between them are totally different!
SolidWork is already very economic when compared to Alias Design Studio or ProE or .....any 'Product Design' software.

I appreciated LW very much because of its quick improvement and special effect, but I don't have much time to learn a new software, I just concentrated on Rhino, SolidWorks and Max.

現在有少少明了, thanks siegfried!
