Resumen
Este estudio presenta UDiFF, un nuevo modelo de difusión para generar superficies abiertas 3D utilizando funciones de distancia sin signo (UDF). También presenta el conjunto de datos UWings y puntos de referencia para evaluar la generación y reconstrucción basadas en UDF.
Área de la Ciencia:
- Gráficos por Computadora
- Inteligencia Artificial
- Procesamiento de Geometría 3D
Sus antecedentes:
- Las funciones de distancia sin signo (UDF) son efectivas para superficies abiertas pero carecen de modelos generativos 3D dedicados.
- Los conjuntos de datos 3D existentes presentan principalmente mallas estancas, lo que dificulta la investigación de superficies abiertas.
- La generación de contenido 3D diverso de superficies abiertas está limitada por las metodologías actuales.
Objetivo del estudio:
- Presentar UDiFF, un novedoso modelo generativo 3D basado en difusión para UDF.
- Permitir la generación condicional y incondicional de formas 3D texturizadas con superficies abiertas.
- Establecer puntos de referencia estandarizados para la generación y reconstrucción de superficies abiertas basadas en UDF.
Principales métodos:
- Se desarrolló UDiFF, un modelo de difusión que opera en el dominio espacio-frecuencia.
- Se implementó una transformada de wavelet aprendible para la generación de UDF, optimizada a partir de datos.
- Se creó el conjunto de datos UWings con 1509 modelos 3D de criaturas aladas.
Principales resultados:
- UDiFF genera con éxito formas 3D texturizadas con superficies abiertas.
- La transformada de wavelet aprendible supera la selección manual en la generación de UDF.
- El conjunto de datos UWings proporciona un punto de referencia para evaluar métodos basados en UDF.
Conclusiones:
- UDiFF avanza en la modelización generativa 3D para superficies abiertas utilizando UDF.
- El enfoque de wavelet basado en datos mejora el aprendizaje de la representación UDF.
- El conjunto de datos UWings y los puntos de referencia facilitan la investigación futura en la reconstrucción de superficies abiertas.

Distance Measurements by Taping
541
Tapes are essential in surveying for accurate, durable, and short-distance measurements. Made from lightweight, nylon-coated steel, they offer flexibility and strength for rugged outdoor use. The nylon coating protects against rust and wear, extending the tape's life. Standard lengths, around 30 meters, are marked in meters and millimeters for precision.Surveyors select tapes based on site conditions and accuracy needs. Lightweight, nylon-coated tapes are commonly used for ease of handling and...

Distance Problem
105
When an object's velocity changes over time, the total distance traveled can be determined by summing small displacement intervals over short increments. This approach approximates the true distance through numerical summation and the use of integral calculus. An estimate of the total displacement can be obtained by measuring velocity at regular intervals and multiplying each value by the corresponding time step.If a runner accelerates over the first three seconds of a race, speed measurements...

Distance Corrections
332
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Design Example: Measuring Distance Between Two Points with Obstructions
452
When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...

The Distance Formula
696
In geometry, measuring the direct distance between two points on a plane is essential in various practical and theoretical applications. Whether in navigation, engineering, or computer graphics, determining the shortest path between two locations involves using the distance formula. This formula is derived from the Pythagorean Theorem, which relates the lengths of the sides of a right triangle. On a coordinate plane, the horizontal and vertical distances between two points serve as the legs of...

Electronic Distance Measuring Instruments
586
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...
