3D models are most often represented as triangulated polyhedra forming a triangle mesh. Non-triangular surfaces can be converted to an array of triangles through tessellation. Attributes from the vertices are typically interpolated across mesh surfaces.
The vertices of triangles are associated not only with spatial position but also with other values used to render the object correctly. Most attributes of a vertex represent vectors in the space to be rendered. These vectors are typically 1 (x), 2 (x, y), or 3 (x, y, z) dimensional and can include a fourth homogeneous coordinate (w). These values are given meaning by a material description. In realtime rendering these properties are used by a vertex shader or vertex pipeline.
First off, I did all the research and thought I should be able to fool the software (CE59 V4.01 USA) by backdating to 2010 as was mentioned here. The software did accept W5 and I was able to upload it to the radio just fine. It would transmit as it should, but it will not receive at all. I found if I go back in the software and select N both receive and transmit work as it should. I just can't get this to wide band. Radio has Firmware V1.85.
I found a copy of (CE59 V2.24w) which supposed to be export software and loaded that and it did the same as above whether I back dated or used the current date. I'm not sure if this is pilot error and I'm overlooking something stupid or is there something in the radio's firmware preventing wide band? I know the radio is designed for narrow band due to FCC rules, but from what I've read people have been successful at using this radio on the ham bands or GMRS. Any help would be greatly appreciated. Thanks.
One other thing I have a vague memory of (I think it was @Radioguy7268may have mentioned it, or maybe @Sshannon) of there being some problems with the filters on some of the vertex radios. Ill see if I can find the post.
Thanks. I'll go through that and see what I can do. What's really odd is I enabled "Off Hook Signalling" and it does intermittently receive. I am playing around with the squelch setting, but not having much luck.
I think I solved it by a roundabout way. These are new in the box radios and the first one I went to program I downloaded from the radio so I can have a virgin file and saved it. I'm now thinking I didn't get a virgin. I did the same with radio #2 and saved it in a safe place and programmed that radio and it worked perfectly. I went and programmed the first radio and it's working. So, now I'm happier than a tick on a hound dog. Thanks everyone for all your help as I was getting beaten into the ground. I always find the stupidest problems!!!
Ok, now since I have both radios receiving I have a new issue. Radio #1 has really poor reception when receiving our local repeater while radio #2 is much better. I've never played with these Vertex before and am wondering if it's a hardware issue or do I need to align it? This is all wide band for GMRS, not narrow.
If that's both radios on the same antenna, coax, etc, where the radio is the only variable, alignment would be my next thought. The line of sight nature of UHF can mean moving the antenna just a foot one way or the other can affect reception though, so.i'd want to rule out all the other possibilities first
Just want to give you guys an update. I had time to go through the radio and did confirm it was a bad ceramic filter. I ordered new filters and just changed them today. It doesn't get any better than this, a $3.00 fix and 30 minutes to rip the radio down and hit it with the desoldering station. All working great and the recieve is hot. Thanks, guys, for all your help as it is much appreciated.
The RenderingServer API has specific functions to update an attribute/skin/vertex region of a mesh instead of the entire mesh. That is a very advanced use as you need to provide the correct stride in the byte array but it is an option.
That only goes for updates on an already created surface with its fixed size. If you need to change the size of the mesh all the rendering arrays need to be resized so at that point you really can just clear the surface and do it from scratch.
I have already gone through the documentation extensively and looked at all the accessible methods, but the explanations are not always clear or not precise enough for certain scenarios.
But the link may be useful to those who pass here without reading the doc first.
After some reflexion and research I think the method "RenderingServer.MeshSurfaceUpdateVertexRegion would be usefull in my case to have a fixed number of vertexs and triangle indexes and just changing their values without having to clear and recreate all the surface?
The byte array that you need to create for the mesh region update is basically a sliced mesh array of what you use for the mesh surface creation just for that stride section that you want to update on the mesh.
Your stride step and data depends on your Mesh.FORMAT and the mesh arrays that you use for the surface. You can find the source code details that tell you how those arrays converted from and to bytes in the driver mesh_storage class of the rendering server. E.g. for the forward renderer it is found here godot/servers/rendering/renderer_rd/storage_rd/mesh_storage.cpp at 36e943b6b20cb7a8a89bc30489c4a81c3e149d74 godotengine/godot GitHub.
Hi all, got a new Vertex VX-2200 and want to program GMRS freq into it. Just the channels for now, then repeaters. I have VX2200 passport software that came with it, and CE-82 software. I think the radio is talking in the Passport software but I get an error in the CE-82 when I try an upload. I don't even know where to start here, can anyone help? I am not sure about all the stuff in there.
The more common LTR version of the VX-2200 should use CE94. Which version are you using?
The Vertex mobiles are pretty much plug and play for programming - you just need to make sure you set up the radio communication configuration to use the correct Comm port. Sometimes the radios get a little fussy for the comm speed that you're using (depending on the cable/chip combination) - but that's usually more of an issue for portables than the mobile units.
Power up the radio, plug the programming cable into the mic jack - if the radio doesn't start beeping at you - double check your connections and configurations. Once the radio is beeping, go ahead and "read" or "Upload" the radio configuration to the computer. Once you have uploaded the configuration, you can make the necessary changes to the programming to fit your desired profile.
What cable are you using to program the radio? If you are not using a genuine FIF-12 from Vertex standard it won't work. I've tried a few knock offs myself to save a few bucks... but in the end you'll need a genuine FIF-12 cable with the appropriate CT-104A lead to the VX-2200 radio.
I seem to have the same Passport model, and I have the CE103 software but I don't see anything that looks like a channel list where I can program Tx/Rx frequencies, tones, etc. It has "Zones" and "Groups", I can program "Zones" with frequencies and tones, but it's not clear if that's the right thing to do, and there is a limit of 28 I think, does that seem right?
For a chain, dynamic programming solution is pretty straight-forward. The state is (number of vertices processed, is the last vertex taken). The value of the state is the minimum cost to cover this part of the graph.
For a cycle, we can use the following observation: either the first or the second vertex is in the cover. So we can reduce it to the 1) problem by removing the first or the second vertex and choosing the best answer.
In the context of linear programming, and assuming that you're using the simplex method to solve your LP's rather than an interior point method, it's most likely that the author means "basic feasible solution" (BFS) here. In geometrical terms, the basic feasible solutions of an LP are vertices of the polytope of feasible solutions.
Since each iteration of the simplex method ends with a basic feasible solution, any optimal solution returned by the simplex method will be a BFS. An algorithm which solves a sequence of linear programming problems in which the constraints do not change (but the objective function varies) by using the simplex method will produce a sequence of basic feasible solutions from this finite set.
At the moment i'm using .obj file format to store 3D models. It's popular, easy to read and parse. The issue is that it stores sufrace normals for each face. This isn't an issue for me yet, but i'm keeping in mind that i have to deal with lights once i'm done with the basics of my engine. This will require vertex normals and not surface normals. I want to avoid vertex multiplication and i want nice, curved surfaces. Blender seems to be unable to store vertex normals, only sufrace normals, is this typical of 3D rendering software and file formats?
