Photograph of a very pronounced double rainbow taken out the window of an apartment building. The horizon is flat with a few buildings in the foreground, but the rainbows themselves are fully unobstructed.
A screenshot of the Geotoy editor showing a smooth tendril-like form rendered on the left and the code generating it on the right. The code includes calls to `trace_path` as well as `rail_sweep`, the latter of which is used to generate the actual mesh
A screenshot of a Geotoy composition showing what looks like a curved piece of metal with a cylindrical hole drilled through it rendered with a gray brushed-metal texture. The code used to generate it is displayed on the right and it contains a call to a function called `trace_path` which contains some 2D drawing commands like move, line, cubic_bezier, and arc.
Colorful curlicues resembling twist-ties twisted into various sorts of spirals and textured with a bright geometric chevron pattern
A diagram created with TikZ which shows the architecture for a denoising autoencoder model. It shows the inputs at the top which are created by concatenating the presence flags and hybrid-normalized rating values, the encoder and bottleneck, and two decoder heads which predict presence and rating separately. The diagram is annotated with fan-out param count for each layer and has nodes to indicate when Swish activation and softmax are applied.
A diagram representing the architecture of a neural network for a recommender model. It shows an input consisting of concatenated presence flags and hybrid-normalized ratings, an encoder hidden layer, a bottleneck layer of size 512, and then two output decoder heads each of which have two hidden layers. The decoder heads are labeled "Presence Decoder" and "Ratings Decoder".
A screenshot of a 3D model created and rendered with Geotoy. It depicts a multi-layered folded shell enclosed in a spherical area, textured and shaded with shiny gold-colored streaks across its surface. The base surface appears rather matte and rocky while the golden streaks are shiny and metallic. It consists of many separate thin layers of material that warp and curl in roughly the same way as each other, yielding an organic look reminiscent of a smooth endoplasmic reticulum.
A screenshot of a 3D model created and rendered with Geotoy. It depicts a multi-layered folded shell enclosed in a spherical area, textured and shaded to look somewhat copper-colored. The surface appears rather shiny and metallic with colors ranging from orange/brown to pink, peach, and crimson. It consists of several separate thin layers of material that warp and curl in roughly the same way as each other, yielding an organic look reminiscent of a smooth endoplasmic reticulum.
A screenshot of a 3D model of a wall with detailed cutouts. A stone wall panel with a repeating lattice of decorative cutouts. The pattern consists of elongated oval shapes arranged horizontally, intersected at their centers by small circular openings. These patterns repeat in a matrix across the surface, creating a perforated screen. Warm light glows from behind the wall, highlighting the depth of the carved openings and casting shadows through the pattern. There is some Geoscript code visible on the bottom of the image which was part of that which generated the model in the scene.
A screenshot of a 3D model of a pedestrian bridge rendered with Geotoy. It shows a bridge with a green fence along either side and several large windows. There is a text editor with code at the bottom.
A screenshot of a mesh rendered in Geotoy. It looks like a sphere with some holes drilled in it that has been split in half sideways. The sphere is textured with a debug texture showing UV coordinates across different parts of its surface
A screenshot of the docs page for geoscript showing details about the `stitch_contours` function. At the top of the docs for that function, there is an expanded example that shows some geoscript code on the left using the function and an image on the right representing the output of running that code. Below the example, there are docs for the function including the function signature, argument names+types+default values, return type, and a description of each argument.
A screenshot of the geotoy web app showing a scene that looks like a roof composed of interlocking shingles. the shingles are a curved shape with a shiny gray stone-like texture. There is a code editor in the bottom left of the screen showing some syntax-highlighted code in a functional-looking programming language. It has variables like `shingle` and function calls like `fan_fill` and contains the code that defines the scene. In the bottom right of the screen, there is some output showing basic stats about the scene and program like runtime in milliseconds, total vertices, and total face count.
Screenshot of a web app showing a 3D model of what looks something like a bird bath rendered along with a code editor with some code in a functional-looking programming language. There's a "run" button along with some stats about how long the code took to run, how many faces/vertices are in the mesh, etc.
A photograph of some graffiti featuring text written in black on a white background. The text says "bro had the texture pack on". There's various other scribbles and illegible text surrounding that writing.
A screen recording of the visual equalizer module I'm building for my browser-based DAW/synthesizer. It shows a line spectrogram plotting a waveform for a low-pitched sawtooth-based synthesizer which is being played. There are handles of varying colors with numbers in them. These handles are dragged around and when they are moved, the spectrogram changes to reflect the altered frequencies in the sound and the timbre of the synthesizer changes as well.
A plot showing the daily percentage change in day length by latitude. The higher the latitude, the more dramatic the changes are, but they all peak around February. Image source: http://wordpress.mrreid.org/2014/10/19/rate-of-change-of-day-length-with-latitude/
A diagram created with TikZ to demonstrate a struct-of-arrays scheme applied to the data structures used to solve Advent of Code 2024 day 9 part 2. There are two rows showing labeled 'Stored Files' and 'Empty Space'. The stored files row has nested cells which contain a length and 4 inner data entries, some of which are empty. The empty spaces row is a simple one-dimensional array which contains a single digit in each cell.
A diagram created with TikZ to illustrate a data structure for solving advent of code 2024 day 9 part 2. It show two rows of nested nodes that represent slots of filled and free space on an imaginary filesystem. The nodes are split in the middle with the left showing a set of contiguous files with different IDs along with their sizes, and the right side shows how much free space is available after that file indicated by the null set symbol. The first row shows the original filesystem layout after parsing and the second shows the result after running the algorithm for the problem.
A diagram showing the tree structure used to solve Advent of Code 2024 day 9 part 2. It has two rows of boxes with arrows pointing to each other in a chain from left to right. The boxes represent slots in the filesystem described by the problem and contain text indicating the contents of each slot like '1 x 1' or '1 x <null set>'. The bottom row has a special split node indicated by [...|...] which branches off in a tree to additional nodes which represent the strategy used by the algorithm to split a free space node into a filled node and a smaller free space node while retaining ordering.
A diagram demonstrating how the algorithm for day 9 part 2 of advent of code operates. It shows rows of cells filled with numbers of blanks. Each row shows the state of the filesystem after one iteration of defragmenting. There are arrows drawn to indicate where files are removed from and written to.
A screen recording of the envelope generator using the constrained Bezier curve with some additional debug elements showing the position of the computed control point in pink, a line between the start and end point in dark red, and a line from the control point to the midpoint between the start and end point in pink. The draggable handle also always sits on that line no matter where the handle is dragged.
