Today I spent some time working on getting the instructions dialogues up. I originally planned on creating a secondary overlay window that pops up given a trigger. Very similar to how to the toast notifications work but instead with a much larger area. The only problem with that is I wanted a clean way to inject custom html into the dialogue box depending on who triggers it. In the case of the toast notification I just pass it a string which is fine given it’s only suppose to be a sure notifier anyways. For the instructions, I may need to add bullets or text stylings depending on what the instructions are for. Strings aren’t going to cut it. ...

I’m a bit more than late for a second devlog but I figured there’s no better thing to call this. I originally made this blog for the purposes of short and sweet devlogs but my recent posts have been bit larger than what I originally intended. I’m hoping with this log to bring that focus back down to just that. Since my previous post, I’ve done a lot of fine tuning of the UI and functionality of the site. One I’m quite happy with was adding draggability to the inputs simialr to other software like Blender. It’s a lot more convenient than typing and allows you to set options easily using mouse only. ...

I recently finished a course in deep learning and wanted to took a look at a few ways I could apply my knowledge to. The idea the came to me was to create an ai music generation model and feed it into my old pianotypes app. Simple right! It’s all broken So I booted up my old, dusty, untouched, forgotten, delapidated, abused, ramshackled, repository, and lo and behold, I can’t get it to run. I tried updating packages, my nodeJS version, moving around code, but nothing worked. In fact, I think updating anything at all just made it worse. Mind you, this project has been mostly untouched for a couple years so it was prone to deprecated libaries and syntax that made it very difficult to remedy. At this point I’ve all but given up on trying to polish a giant heaping pile of rust. ...

I’ve been working on migrating my old PianoTypes project over from Vue to Svelte. So far the syntax has been much cleaner to use and has been an overall a great experience. My first and primary pain point thus far has been implementing a global reactive state for the piano. The Problem In Vue, it’s possible to add a reactive wrapper to any object. In my case, I had created a class containing all of the piano data and property methods so all I had to do was wrap this class in the wrapper and state is maintained across all instances of my piano class. ...

Vertex Shaders So far, I’ve been primarily writing 2D shaders to create patterns on a flat canvas. In practice, shaders can also be applied to 3D objects to manipulate not only their textures but also their shape. To start, let’s take a look at a simple 2D shader placed on a 3D cube. Notice that the texture remains flat but is effectively cropped onto the projection of the cube. Ideally, we’d like the texture to wrap over the cube instead. ...

While writing this blog, I’ve been constantly finding a need to include various JavaScript libraries such as graphics libraries or text processors. I love the simplicity of Markdown but sometimes it can be really helpful to include more meaningful content and visuals to better illustrate a certain topic or idea. My most recent endeavor was adding an easy way to render shaders within each of posts which turned out to be a more painful task than I originally anticipated. Here, I hope to document some of my process of importing modules and hopefully make it easier for whoever is reading to import modules into their own Hugo blog. ...

Fractals are built off of a single pattern or formula, repeated constantly with smaller and smaller transformations. In glsl, this idea translates nicely into iterative coding with for loops. How to Make a Fractal I’ll be following kishimisu’s guide on shaders. Create a Shape First off, we can start by creating some base patterns that we want to design our fractal off of. In this case, we can start with a simple circle. ...

I’ve been thinking about drawing more casually, inspired by how others seem to sketch just for the joy of it, not tied to contests or big projects. I really admire how they just go with whatever they’re feeling, letting their ideas spill onto the page without worrying about a specific style. I’ve tried a few doodles myself, and it’s kind of neat to see them starting to share a certain look, even if I’m not sure what it means yet. ...

Intuition of 3x3Matrix Transformations Rotations can be achieved by locking the desired axes of rotation and transforming the rest of the axes by \(sin\) and \(cos\). 3x3 matrices can be used to bend the coordinate space in 3 dimensions, effectively allowing any desired transformations to objects in that space. As the coordinate space is being transformed, it’s helpful breaking up the matrix into its unit vectors $$ \vec{a} = x\begin{bmatrix}1\\0\\0\end{bmatrix} + y\begin{bmatrix}0\\1\\0\end{bmatrix} + z\begin{bmatrix}0\\0\\1\end{bmatrix} $$ ...

Neural Networks See Machine Learning How do you decide how many neurons to use per layer? One way is to start with all layers uing the same amount of neurons and continue adding them until they start overfitting the data Dropout: Regularlization technique to avoid overfitting. Leaves out data to better deal with general cases. 20%-50% dropout is a good starting range. Momentum: Helps finding the direction of next descent and prevent oscillations. Typical choice between 0.5 to 0.9 Epochs #times the whole training data is shown to netowrk during training. 1 epoch = one forward and one backward pass of all training data Back Propagation See Machine Learning ...
