Reverse Zoom In Rhino

admin

Once a 3D model is in mesh form, it's hard to recreate a smooth NURBS object from it. There is much info available on the subject of reverse engineering and its difficulties; here is one article on how to attempt this with Rhino tools. There are also several specialized reverse engineering software packages to partially automate this process.

Rhino Resource Partners LP Completes 1-for-10 Reverse Unit Split

April 19, 2016 - Rhino Resource Partners LP announced today that it has completed a 1-for-10 reverse split on its common units and subordinated units. Pursuant to the reverse split, common unitholders received one common unit for every 10 common units owned on April 18, 2016 and subordinated unitholders received one subordinated unit for every 10 subordinated units owned on April 18, 2016. Any fractional units resulting from the reverse unit split were rounded to the nearest whole unit.


As adjusted for the reverse unit split: Rhino’s common unit count was reduced from approximately 76.9 million outstanding common units to approximately 7.7 million outstanding common units post-split, and Rhino’s subordinated unit count was reduced from approximately 12.4 million outstanding subordinated units to approximately 1.2 million subordinated units post-split. The closing sales price of Rhino’s common units on April 18, 2016 was $0.34 per common unit, which adjusted for the reverse unit split would be $3.40 per common unit.

As previously announced, the reverse unit split is intended to increase the market price per unit of Rhino’s common units in order to comply with the New York Stock Exchange (“NYSE”) continued listing standards. The NYSE suspended trading of Rhino’s common units on December 17, 2015 for failure to comply with the NYSE continued listing standards. Rhino is appealing the NYSE’s suspension and delisting of its common units. There can be no assurance that Rhino will be successful in its appeal and that its request for continued listing on the NYSE will be granted.

Rhino common units will begin trading on a split-adjusted basis today, April 19, 2016. Rhino’s common units trade on the OTCQB under the symbol “RHNO.” The new CUSIP number for Rhino’s common units is 76218Y 202.

Preliminary Design – Sales Impressions – Fairing – Surface Quality Analysis – Hydrostatics – Lines Plans – Kick Start Example hulls

Introduction

Rhino can be applied for a lot of tasks when hull shapes are involved:

Initial Design/ Sales Impressions/ Hull Optimization/ Final Design/ Fairing for Production/ Reverse Engineering: Hull from GA, Lines-Plan, point cloud or measurements.

Every type of ship hull can be designed and modeled accurate and fair in Rhino with several techniques and strategies. Each strategy has its pros and cons depending on the type of ship hull and purpose of the 3d model of the ship hull. Most important factors are whether the strategy allows fast editing and easy fairing for a flexible workflow and accurate results. The Rapid Hull Modeling Methodology offers it all, for nearly every type of ship and yacht hull shape, which makes it so attractive and valuable. The Rapid Hull Modeling Methodology was originally developed by Bas Goris and Phil Shapiro more than 10 years ago. Since then it is further developed by RhinoCentre.

Keep in mind

  • Most important is that the user defines the quality of the surfaces and not Rhino. Therefore proper training is crucial to avoid mistakes.
  • Most challenging in Rhino is to create hulls as a single surface instead of surface patch-work. The reason for this is that it is easier to fair a single surface hull. Also editing the shape later is much more convenient with a single surface hull
  • Some types of ship hulls are impossible to model as a single surface in Rhino. One example is a ship hull with an aft bulb when a lot of control is desired for accurate reverse engineering of the aft bulb. Another example is modeling a twin-skeg arrangement as a single surface. In that case the T-Splines Rhino plugin is the next solution
  • Both double curved round bilge type of hulls as single curved (developable, multi chine) type of hulls can be modeled in Rhino.

Goals of the training

  • Create a ship hull from scratch or modify an existing example of a ship hull
  • Generate loft curves which define the shape of the surface of the ship hull
  • Edit loft curves for:
    • Creating the desired ship hull type
    • Fairing of the ship hull
  • Generate a lines plan with sections, waterlines and buttocks
  • Analyze the shape and characteristics of the hull
    • Regarding smoothness
    • With Rhino Hydrostatics

Testimonial
“I have been a Rhino user for about fifteen years and I considered myself a competent modeler. However, I learned more about Rhino in four days at Rhinocentre than I did in fifteen years of teaching myself. I highly recommend this course.”

First, every exercise is explained with a movie. After that, below the movie, the exercise is written out step by step so you can practice yourself. You also receive tips, cautions and notes to understand better what you do and learn more than is explained in the exercises.

Display Mesh

Surfaces in Rhino are described with NURBS mathematics. However graphics cards can only show the NURBS surfaces in wireframe display. To show the surfaces in shaded or rendered display Rhino generates automatically a so called ‘render mesh’ for each surface with a default smoothness. This explains that sometimes the edge curves of a surface show smooth and accurate but the surface itself shows rough and ugly. Especially during fairing with the Glossy for Fairing display it is important to have a smooth render mesh.

Exercise 32: Display Mesh

  • Switch the Perspective viewport display to ‘Glossy for Fairing’
  • Select the loft surface
  • Zoom in at the bow area
  • In the Object Properties menu select the checkbox for a Custom Mesh (Fig. 62).
  • Click Adjust. The ‘Polygon Mesh Options’ dialog pops up (Fig. 62)
  • Click at Preview and look at the mesh faces on the surface
  • Move the slider to ‘Fewer polygons’ and click at ‘Preview’ again. Notice the large mesh faces along the surface and the straight lines at deck level. This doesn’t look smooth
  • Move the slider to ‘More Polygons’ and click ‘Preview’ again. This looks much better. However the bulbous bow is still very rough

  • Click ‘Detailed Controls’ in the Simple Mesh Options dialog and set the values according to Fig. 63
  • Click Preview again. The mesh faces distribution is much more refined now.
  • Press OK to accept these settings and examine the display quality of the surface.

It is important to understand that the more refined the Display Mesh is, the larger the file size will become as each Mesh face has to be described. Furthermore editing the shape of the hull is slower with a detailed render mesh as it has to be recomputed over and over again. On the other hand a sufficient level of detail of a render mesh is necessary to be able to examine the surface smoothness. Finding the proper balance here is very important.
