    Ready to use plants FormZ/VRay

    I find Vizpark to be great. I've only ever used the Maxwell versions of the models but they have Vray versions as well. Des

    Match view question

    It all depends on the lens/camera used. There are FOV (Field Of View) calculators available on line which allow you to input the sensor size etc. to get the angle. But I prefer to align the views manually using known reference points. It's very important to set your Image Options to the same aspect ratio to the original photo. I usually make a copy of the original photo (6000x4000) and reduce it to say 2400x1600 before importing as a background image in Fz, it's quicker to load etc. and I can resize later before I go to render. Take this example below of an older project; I knew the position I took the shot and was able to draw a circle on the plan. Draw on a reference layer with known features, go to perspective view and use Edit cone of Vision to point and adjust the camera lining up the known features and plan, sometimes the spin needs adjusting as well. As a check you can see the focal comes out at 28.33mm with an angle of 64.86º. If I open the original photo and check its EXIF data the focal length is 18mm but remember that each lens used has a "multiplier" number. Mine just happens to be 1.6, so multiply the exif data focal length by 1.6 and you get 28.8 which is not far off at all considering the farther away the centre of interest there is a slight bend in the angle. Also consider your camera height (eye level), if you have the level of the ground level great but it usually needs adjusting as well. So going back to the Match View tool, I only use it as a starting point for some projects where I have modelled a certain amount of existing features accurately (not usually though) so I have points to snap to when lining it up. It can be hit and miss though.

    Rounding Question

    I just tried it with all of your settings with no problems at all. How are you selecting the edges? FormZ v9.0.4.2 on 2013 iMac running Catalina 24GB ram

    Match view question

    I usually use a 50mm lens with no zoom which gives a cone of vision of about 63º. I also mark my position of the camera on a map and set the camera from there. I also use google earth to grab an overview (or an imported location plan with features) and model in "anchors" (extruded objects) where known features are in the photo, that way I can just point the camera in the right direction, and fine adjust the angles and direction as needed. I find match view works best when more advance existing structures are modelled but that is not always the case, although it's great for matching aerial views as a starting point.

    Very cool indeed! Well done 👏
  7. Thanks for posting this Chris. It's the type of modelling I would have thought to be the best method for an accurate model. It'd be nice to be able to convert a nurbs model like this to a Quad Mesh afterwards the same way it can be done from a Sud-D object.

    formZ Sub-D introduction

    Thanks Chris, I'm looking forward to the other two videos. One thing, the video resolution is really low at 360p so it's hard to see any detail. Des

    Polygon cages for smoothing

    That's excellent Chris, thanks for taking the time to do this and for posting it. Yes, I'd love to see your workflow so when you have time, post your method. The first thing I did when I downloaded your model was to do a sub-division swap to see the frame. Cheers, Des

    Polygon cages for smoothing

    Thanks for posting that Chris, the sub-D method gives better results, the geometry just looks better. When I tried the other splines/nurbs method, I had initially wanted to do a sub-D of 1/8 of the revolve created from the swept splines but couldn't spend more time on it so used nurbs in the end. If I get time later I'll try to do a combination of the two maybe. Just wondering if anyone has an actual classic coke bottle at hand that they could measure accurately and post the sizes here? I think the exercise here is to be able to model it accurately so we'll need measurements. I'd be interested to see this exercise develop to a conclusion of the nicest (not necessarily the quickest) method.

    Polygon cages for smoothing

    There are some here who are very good with sub-Ds (you know who you are!) and I'm sure they could come up with a workflow for those. However, I made my first attempt using splines and nurbs, here is the result so far. It needs more playing around with the splines (see the indents) but it shows that this approach works fine and produces a nice smooth surface. I made two splines, one for the indent, duplicated it and edited it for the bumps. Multi rotated them within 45º (using 45 as I'm thinking 8 sectors in a coke bottle?). Nurbs lofted them (selection order is important), rotate duplicated 7 times and stitched them together. CokeBottleAttempt01.zip

    I think this is a good discussion and I'm interested how other people would approach this. I remember doing a large Fanta bottle many years ago but it was less detailed than the coke bottle. It was created using similar process described above (revolve, booleans, rounding etc.). One thing I am sure of is that any splines to be used initially must be good quality (not imported) and good information of the object (decent photos). When taking photos of an object for reference and tracing I usually use a zoom lens and take from really far back and zoomed in to reduce the perspective (narrow cone of vision). Otherwise I think FormZ could produce a beautiful model using the tools available. Clean modelling is what interests me without breaking the bank regarding poly count, preferably smooth geometry for adjustment. Watching with interest and if I find time I'll jump in as well.. Des

    Maxwell 5.1 Released!

    Just want to say I installed Maxwell with FormZ9 a few days ago and all is working well. I started my first paying job with FZv9 and Maxwell V5.1 and so far there are no issues. In fact it seems to run better than ever. Des
