Bricksmith vex iq4/10/2023 ![]() ![]() ![]() I actually only used half-and-half because it's what I hit on first that worked (model a half-sphere, get it texmapped, move on), I'm glad I didn't spend a bunch of time trying to use only one TEXMAP statement. I never figured it would take so many years, though It was MEANT to be really straightforward (create a set of U-Vs, the style would just change how they were calculated, the main loop should not have had to change much). We opted to try to make it as easy to implement as possible. The CYLINDRICAL and SPHERICAL specs were from the same book. The original PLANAR work came straight from the OpenGL docs as a suggestion for this type of mapping. It's an optional (currently enabled) feature though as I wasn't sure the spec was intended to support >180 deg (by limiting this on the authoring side.)Īlso there will still be problems at the poles when using certain orientations of the texture (resulting from misalignment of vertices). So I'm using longitude / latitude mapping to generate the texture coordinates to get around that. The current implementation in LDCad uses a hack to make full sphere mapping possible as the literal spec will cause problems past 180 degree. This was easy for me to get working, and it looks fantastic in LDCad! Plates are ideal for building robot towers, plows, and any other application where a strong structural component or a large mounting surface area is needed.Roland Melkert Wrote: Joshua Delahunty Wrote:Congratulations, Roland. This pattern is a line of mounting holes and then a line of mounting holes which is off-set by ½ a pitch. Plates have a mounting hole pattern which matches the 2x Beam mounting hole pattern. They are available in a variety of lengths and widths. Plates are great for adding structural support to a robot. Specialty beams can be used in many different robot structures such as mounting a VEX IQ Brain, building a claw, or creating a hook for the robot to hang from a bar. To assist with a correct beam identification, it can be helpful to match the beam up with the illustrations on the Kit Content Poster or use the Check Angle diagram found in the beginning of most VEX IQ Robot Build Instructions. The Angled Beams look very similar to one another and can be easily misidentified. In an assembly which may need extra strength, these Beams can be connected together in layers which will significantly help them from bending and twisting. There are 30 o, 45 o, and 60 o Angle Beams which allow the VEX IQ building system to have numerous options for assembly angles. There are Right Angle, Offset Right Angle, and Tee shaped Beams which provide a solid 90 o corner. Specialty Beams are uniquely shaped and angled beams. However, if the center mounting hole of the beam needs to be used for a Connector Pin, Standoff, or Shaft, the 2x2 Beam must be selected because this location on the Lock Plate is a square hub. The 2x2 Shaft Lock Plate is often confused with the 2x2 Beam. They are compatible with all of the Corner Connectors, however using the 2x version of Corner Connectors provides two points of connection which creates a better attachment between parts. The 2x beams are ideal for assembling robot chassis, lifts, and arms. This arrangement of mounting holes allows for a multitude of assembly options. These center holes also run the length of the beam, however they are offset by ½ a pitch from the outside rows of holes. Each 2x Beam has 2 rows of mounting holes running the length of both outside edges, plus the beam has a set of center row holes. The 2x Beams have a width of 2 pitch units. These three Beams all have a center mounting hole in addition to their other mounting holes. There are three exceptions to this rule, these are the 1x2, 1x4, and 1圆 and 1x16 (2nd gen) Beams. In most cases, the pitch length equals the number of mounting holes running the length of the Beam. The 1x Beams come in both even and odd pitch lengths ranging from 2x pitch through 20x pitch. They have a width of one pitch unit(12.7 mm / 0.5"), which in this case equals a width of one mounting hole. The 1x Beams are not as structurally rigid as the other structural pieces, however they can be connected together in layers with one another which will significantly help them from bending and twisting. For example, a 1x Beam can be used to make a supporting connection between a tower and a drivetrain. ![]() They are ideal for assembling specialized structures such as the grabbers for a claw assembly or as a general part to make connections on the robot. The 1x Beams are the narrowest of the structural components. The VEX IQ structural parts include: Beams 1x Beams ![]() This picture illustrates IQ (1st gen) Beams and Plates. ![]()
