Nice Topology question for problem

Gikkio

Hi guys

i search for better my modeling technique, about topology.
I have some doubt for a topology on piece that have a curve lines, smooth hard surface.


i have this to Retopology. What QUAD MODELING TOPOLOGY is correct for a piece like this? 
You can draw on imae if you want. Software BLENDER




This is the SIDE VIEW, see that curve? how can i create a correct topology on a hard surface piece?

Gikkio

Dawn  i can't solve this geometry problem.....

model the silhouette and do an inset, then extrude and add support loops to the extruded part

Gikkio

"INSERT" you talk about a internal extrusion? i'm not understain.
in BLENDER 

Gikkio

like this ? 

start from external, towards the inside of the geometry?

sorry, i overlooked that you are trying to retopo
but you can use this as a base, and then it really depends on the polycount you are aiming for
i would bevel the edge and remove every vertex that does not add to the silhouette

if this thing does not get deformed by an animation, the topology on the flat surfaces does not really matter that much, so just remove everything that does not add to the silhouette, no need to keep everything in quads
avoid having long thin triangles though

Gikkio

No, i'm sorry to you , because i don't tell you that these are exercises to improve my topology, and to become good in the quad topology.

using blender to model, I never learned to use a topology into triangles, so you do not even know how to unwrap.

The "goal" is to improve my topology in order to always have a retopo and an always clean unwrap, for all (organic and hard) my model.
i want to learn how to model ALWAYS .  

 Imade it, at last! 1 h. of try!! 

I think is a correct topology, the subsurf don't give artifacts, the edges They are flowing in a circular manner, and i can add the loops for hard the edges without problem. So is work fine.

This is a correct topology? Is clean?
ty!!

i think you have a misunderstanding here

for subd modeling you want to have a good topology for subdiving, but this is uasually for your highpoly model which only serves for baking your maps out
retopo means to create a lowpoly model, which is the actual model used in the engine later on
since the lowpoly model does not get subdivided, you don't need to have all quads and clean loops
usually you want to cut down all polygons that dont add to the silhouette here (special cases ; animation, tesselation...)

so i guess what you want to know i how to do subd modeling
so best start from zero



this video gives you a pretty good insight in how to start out

and then take a look at this thread, which is kinda dedicated to this stuff

ok!
 The fact is that I have always seen tutorials in English, especially spoken, so I never got it.:)
but i know the hard surface. Sorry is my bad ENG.

The model that you see up, is not a model. Is a simple curve convert in mesh, but only to show you the form that i need to model. 
To make a screenshot, for ask here " ok guys what topology i use now". 

The question is how I model that piece I posted? what hard surface technique i need to use to high poly model that piece? 

I tank about RETOPO but is not a real retopo is a new modeling of the piece that i have made for sohow it in tis forum (with curve). 
sorry for that.
